Glasgow vs Edinburgh Weather: Which City Is Wetter?

Glasgow and Edinburgh have noticeably different climates despite being only around 70 kilometres apart. Glasgow is substantially wetter overall, while Edinburgh is generally drier and slightly sunnier; temperatures are much closer, so the biggest year-round difference is rainfall rather than cold.

The idea that Glasgow has “worse” weather than Edinburgh is rooted in a genuine climatic difference. Glasgow sits on Scotland’s western side and receives more Atlantic rainfall. Edinburgh lies farther east and benefits from the rain-shadow effect created by Scotland’s higher ground.

The comparison is not simply about whether one city feels colder. Weather quality involves rainfall, rainy days, sunshine, wind, frost, temperature and seasonal patterns. Long-term climate averages provide a more reliable comparison than individual forecasts or memorable wet days.

The most useful benchmark is the Met Office 1991–2020 climate normal, which uses a standard 30-year period for assessing typical conditions. At Glasgow Bishopton, the average annual rainfall is 1,370.23 mm, compared with 784.29 mm at Edinburgh Gogarbank. Glasgow therefore receives about 586 mm more rain each year.

That difference is substantial. Glasgow also records 181.22 days with at least 1 mm of rain annually, compared with 137.43 days in Edinburgh. Edinburgh receives less rain and experiences fewer wet days.

Why does Glasgow receive so much more rain than Edinburgh?

Glasgow receives more rainfall because its western position exposes it to Atlantic weather systems, while Edinburgh lies east of Scotland’s main uplands and benefits from a rain-shadow effect that reduces rainfall reaching the city.

The geography of Scotland explains much of the difference.

The United Kingdom is strongly influenced by prevailing westerly winds. Atlantic weather systems frequently approach Scotland from the west. These systems carry substantial moisture.

When moist air reaches western Scotland, it encounters higher terrain. Air is forced upwards over hills and mountains. Rising air cools, condensation increases and rainfall develops. This process is called orographic enhancement.

The Met Office identifies western Scotland as one of the wettest parts of the United Kingdom. Mountainous locations in western Scotland receive particularly high rainfall totals. The Met Office also identifies a clear west-east rainfall pattern caused by prevailing westerlies and the influence of high ground.

Glasgow sits within this wetter western climate zone. Edinburgh is located on Scotland’s eastern side, where rainfall totals are considerably lower.

This creates a major climatic distinction between the two cities. Glasgow does not simply receive occasional heavier showers. Its long-term climate produces considerably more precipitation across the year.

The difference is especially important during autumn and winter, when Atlantic depressions frequently affect Scotland. The Met Office states that Glasgow receives much of its rainfall from Atlantic depressions affecting Scotland throughout the year, with autumn and winter particularly important.

Is Glasgow wetter than Edinburgh in every month?

Glasgow is wetter than Edinburgh in every month of the 1991–2020 climate period, with the largest differences generally occurring during autumn and winter when Atlantic weather systems bring frequent rainfall to western Scotland.

The monthly figures demonstrate how persistent the difference is.

In January, Glasgow averages 157.32 mm of rainfall, while Edinburgh averages 73.01 mm. Glasgow therefore receives more than twice as much rainfall in the first month of the year.

February records 124.97 mm in Glasgow compared with 61.07 mm in Edinburgh.

March records 112.37 mm in Glasgow compared with 52.49 mm in Edinburgh.

April narrows the difference, but Glasgow remains wetter, with 73.18 mm against Edinburgh’s 45.87 mm.

May records 71.91 mm in Glasgow and 50.17 mm in Edinburgh.

June records 80.78 mm in Glasgow and 68.77 mm in Edinburgh.

July records 91.94 mm in Glasgow and 71.85 mm in Edinburgh.

August shows a stronger contrast again. Glasgow averages 107.06 mm, while Edinburgh records 74.71 mm.

September records 109.36 mm in Glasgow and 55.17 mm in Edinburgh.

October produces 135.67 mm in Glasgow compared with 82.66 mm in Edinburgh.

November records 144.98 mm in Glasgow against 73.65 mm in Edinburgh.

December is one of the wettest months in both locations. Glasgow averages 160.69 mm, while Edinburgh averages 74.87 mm.

The pattern is therefore consistent rather than seasonal in only one part of the year.

Does Glasgow also have more rainy days than Edinburgh?

Yes. Glasgow has considerably more wet days than Edinburgh, with 181.22 days recording at least 1 mm of rainfall annually compared with 137.43 days at Edinburgh Gogarbank during 1991–2020.

Rainfall totals and rainy-day frequency measure different aspects of climate.

A city can receive a large annual rainfall total from relatively few intense events. Another city can experience frequent light rain without accumulating as much water.

Glasgow performs worse on both measures in this comparison.

The Met Office records 181.22 days per year with rainfall of at least 1 mm at Glasgow Bishopton. Edinburgh Gogarbank records 137.43 such days.

That represents roughly 44 additional measurable-rainfall days each year in Glasgow.

The difference is particularly clear during winter.

Glasgow records an average of 18.18 rainy days in January, compared with 13.30 in Edinburgh.

In December, Glasgow records 18.02 days, compared with 13.08 in Edinburgh.

November records 18.00 days in Glasgow compared with 12.86 in Edinburgh.

October records 17.21 days in Glasgow compared with 13.00 in Edinburgh.

The pattern confirms that Glasgow’s wetter reputation is supported by long-term observations.

Is Glasgow colder than Edinburgh throughout the year?

No. Glasgow is not consistently colder than Edinburgh. The two cities have very similar temperatures, while Glasgow often has slightly higher daytime and nighttime averages in the 1991–2020 Met Office records.

Temperature is where the popular comparison becomes more complicated.

The 1991–2020 Met Office averages show an annual mean maximum temperature of 12.70°C at Glasgow Bishopton and 12.80°C at Edinburgh Gogarbank.

The annual mean minimum temperature is 5.71°C in Glasgow and 5.78°C in Edinburgh.

These figures show almost no meaningful difference in annual average temperature.

Glasgow is not therefore a colder city in the straightforward sense.

The monthly figures also show close temperatures.

In January, Glasgow has an average maximum of 6.69°C, while Edinburgh records 6.90°C.

In July, Glasgow averages 19.30°C, while Edinburgh averages 19.40°C.

In August, Glasgow records 18.93°C, compared with 19.17°C in Edinburgh.

In December, Glasgow averages 6.79°C, while Edinburgh averages 7.02°C.

The temperature gap is therefore small.

This distinction matters because people often interpret wetter conditions as colder conditions. Rain, cloud, wind and damp surfaces influence how weather feels, but rainfall totals do not establish that one city has a colder climate.

Does Edinburgh get more sunshine than Glasgow?

Edinburgh receives slightly more annual sunshine than Glasgow in the 1991–2020 Met Office records, although the difference is modest compared with the much larger contrast in annual rainfall between the two cities.

Edinburgh Gogarbank records 1,363.43 hours of sunshine per year in the 1991–2020 period.

Glasgow Bishopton records 1,344.10 hours.

The difference is only about 19 hours annually.

This is important because the sunshine difference is much smaller than the rainfall difference.

Edinburgh is clearly drier, but it is not dramatically sunnier according to these specific station averages.

Some months favour Glasgow.

May provides a notable example. Glasgow records 197.20 hours of sunshine, compared with 189.50 hours in Edinburgh.

July also shows Glasgow slightly ahead, with 162.68 hours compared with Edinburgh’s 160.93 hours.

Other months favour Edinburgh. September records 125.48 hours in Edinburgh compared with 117.94 hours in Glasgow. October records 94.12 hours in Edinburgh against 84.86 hours in Glasgow.

Sunshine therefore does not explain the cities’ reputational difference as strongly as rainfall does.

Is Glasgow windier than Edinburgh?

Glasgow is not generally windier than Edinburgh at the Bishopton and Gogarbank stations used for the 1991–2020 comparison; Edinburgh records a higher annual average wind speed, while local exposure and urban geography influence actual conditions.

The Met Office station data show an annual mean wind speed of 7.57 knots at Glasgow Bishopton and 8.15 knots at Edinburgh Gogarbank.

That gives Edinburgh the higher annual average in this specific comparison.

The monthly pattern is also interesting.

Glasgow averages 8.50 knots in January, while Edinburgh averages 9.56 knots.

In February, Glasgow records 8.75 knots compared with 9.60 knots in Edinburgh.

During July, Glasgow averages 6.65 knots, while Edinburgh records 6.74 knots.

The difference is small during summer but becomes more noticeable during some winter months.

This demonstrates why a simple “bad weather” ranking is unreliable. Glasgow has significantly more rain, but Edinburgh has higher average wind speeds at these comparison stations.

Weather experience therefore depends on which variable is being measured.

Which city has more frost, Glasgow or Edinburgh?

Edinburgh records slightly more air-frost days than Glasgow in the 1991–2020 station data, showing that Glasgow’s wetter climate does not translate into more annual frost or consistently colder winter conditions.

Glasgow Bishopton records 45.57 air-frost days per year.

Edinburgh Gogarbank records 48.01 air-frost days.

The difference is relatively small but it favours Edinburgh for frost frequency.

Both locations record zero average air-frost days during June, July and August.

Glasgow records 9.87 frost days in January, while Edinburgh records 9.99.

December records 10.30 frost days in Glasgow and 10.63 in Edinburgh.

The figures reinforce the same conclusion seen in temperature data. Glasgow’s wetter conditions are not evidence of a colder climate.

Why does Glasgow feel wetter than the statistics suggest?

Glasgow feels particularly wet because it combines high annual rainfall with frequent measurable-rainfall days, especially during autumn and winter, creating repeated exposure to damp conditions rather than isolated heavy rainfall events.

The distinction between rainfall amount and rainfall frequency is central.

Glasgow receives approximately 1,370 mm of annual rainfall at Bishopton. That rainfall is distributed across 181 days with at least 1 mm of precipitation.

This creates repeated wet-weather exposure.

A resident does not experience the annual rainfall total directly. Daily weather determines whether outdoor journeys, commuting, walking, cycling and leisure activities encounter rain.

Glasgow’s winter pattern is particularly significant.

December averages 160.69 mm of rainfall and 18.02 days with at least 1 mm. January averages 157.32 mm and 18.18 rainy days. November averages 144.98 mm and 18.00 rainy days.

That frequency gives Glasgow a persistent wet-weather profile.

Edinburgh’s corresponding winter figures are lower.

December records 74.87 mm and 13.08 rainy days.

January records 73.01 mm and 13.30 rainy days.

November records 73.65 mm and 12.86 rainy days.

The difference is clear in both volume and frequency.

Is Glasgow’s wetter climate caused mainly by its location?

Yes. Glasgow’s western Scottish location is the principal climatic factor behind its higher rainfall, because Atlantic air reaches western Scotland first and rising terrain enhances precipitation before weather systems continue toward eastern Scotland.

Geography controls the broad structure of Scottish rainfall.

Glasgow is positioned on the River Clyde in western Scotland. Its regional climate is strongly influenced by Atlantic weather.

The Met Office describes Glasgow as one of the wettest cities in the United Kingdom. Its climate science material identifies Atlantic depressions as an important source of rainfall.

Edinburgh sits on the eastern side of Scotland near the Firth of Forth. Weather systems travelling from the Atlantic have already crossed substantial terrain before reaching the east.

The mountains and uplands remove moisture from incoming air through orographic rainfall.

This produces a rain shadow, meaning an area receives less precipitation on the sheltered side of higher terrain.

The Met Office identifies this west-east rainfall pattern across the United Kingdom. Western and mountainous regions receive substantially more rainfall, while eastern areas receive less because of prevailing westerly weather systems and intervening high ground.

Does Glasgow’s urban environment affect its weather?

Glasgow’s urban environment influences local temperatures and weather conditions, but its major rainfall difference from Edinburgh is primarily geographical and regional rather than simply an urban effect.

Cities create local climate effects.

Buildings, roads and other urban surfaces absorb and retain heat. This contributes to the urban heat island effect, where built-up areas remain warmer than surrounding rural locations under suitable conditions.

The Met Office identifies the urban heat island effect as one factor influencing Glasgow’s climate. It also identifies Glasgow’s low-lying river-basin location and surrounding geography as important influences.

These effects do not explain Glasgow’s much higher annual rainfall by themselves.

The difference between 1,370.23 mm in Glasgow and 784.29 mm in Edinburgh is primarily consistent with the broader west-east Scottish rainfall pattern.

Station location also matters. Bishopton is west of Glasgow’s central urban area, while Gogarbank is on the western edge of Edinburgh. Climate statistics therefore describe specific observing locations rather than every street within each city.

Which city has better weather for outdoor activities?

Edinburgh generally provides more reliable conditions for outdoor activities because it receives substantially less rainfall and fewer wet days, while Glasgow remains suitable for outdoor activities with planning based around frequent Atlantic rainfall.

For outdoor planning, rainfall frequency is particularly important.

A visitor planning a walking route, sightseeing day or cycling trip needs to know how often rain interrupts outdoor conditions. Edinburgh’s lower rainfall and fewer rainy days provide an advantage on long-term averages.

Glasgow still has significant outdoor opportunities throughout the year. The city and surrounding areas include parks, riverside routes and access to the wider landscapes of western Scotland.

The key practical distinction is preparation.

Glasgow’s climate supports year-round outdoor activity, but waterproof clothing and flexible plans are especially relevant during autumn and winter.

Edinburgh also experiences rain throughout the year. Its drier climate does not mean consistently dry weather.

Neither city provides a guarantee of dry conditions on an individual day. Climate averages describe long-term probability patterns, while forecasts determine the weather expected for a particular date.

Does Glasgow have worse weather all year round?

Glasgow does not have worse weather in every category all year round. It is substantially wetter, but temperatures are similar, Edinburgh is windier on the cited annual averages, and Glasgow receives slightly less annual sunshine.

The phrase “worse weather” depends on the measurement.

If worse means more rainfall, Glasgow clearly ranks wetter.

If worse means more rainy days, Glasgow also ranks wetter.

If worse means colder temperatures, the data do not support that conclusion.

If worse means more frost, Edinburgh records slightly more annual frost days.

If worse means stronger average winds, Edinburgh records the higher annual average at the two cited stations.

If worse means less sunshine, Glasgow records slightly fewer annual sunshine hours.

The strongest and most consistent difference is rainfall.

The 1991–2020 data show:

Glasgow: 1,370.23 mm annual rainfall.

Edinburgh: 784.29 mm annual rainfall.

Glasgow: 181.22 days with at least 1 mm of rainfall.

Edinburgh: 137.43 days.

Glasgow: 1,344.10 sunshine hours.

Edinburgh: 1,363.43 sunshine hours.

Glasgow: 45.57 air-frost days.

Edinburgh: 48.01 air-frost days.

These figures provide a more accurate answer than the general reputation of either city.

What does the long-term climate record say about Glasgow versus Edinburgh?

The long-term record confirms that Glasgow has a distinctly wetter climate than Edinburgh, while temperature, frost, wind and sunshine differences are smaller and vary by season, station and weather pattern.

The comparison is strongest when it uses the same climate-normal period.

The Met Office’s 1991–2020 dataset provides a consistent 30-year baseline for both locations. This period captures a broad range of Scottish weather conditions and reduces the influence of individual unusual years.

The Glasgow Bishopton data show an annual maximum temperature of 12.70°C, minimum temperature of 5.71°C, rainfall of 1,370.23 mm, 181.22 rainfall days and 1,344.10 sunshine hours.

The Edinburgh Gogarbank data show an annual maximum temperature of 12.80°C, minimum temperature of 5.78°C, rainfall of 784.29 mm, 137.43 rainfall days and 1,363.43 sunshine hours.

The rainfall difference is therefore the defining feature.

The temperature difference is only 0.10°C for average annual maximum temperature and 0.07°C for average annual minimum temperature.

Annual sunshine differs by approximately 19 hours, while annual rainfall differs by approximately 586 mm.

This creates a clear hierarchy of climatic differences.

Rainfall is the dominant contrast. Temperature is comparatively similar. Sunshine is close. Frost and wind show different patterns.

How should Glasgow residents interpret the city’s weather reputation?

Glasgow’s reputation for poor weather has a strong statistical basis for rainfall, but it should not be interpreted as evidence that the city is colder, frostier or consistently more severe than Edinburgh across every weather measure.

The data support a precise description rather than a broad judgement.

Glasgow is a wetter city.

Edinburgh is a drier city.

Glasgow receives more annual rainfall and has more measurable-rainfall days. The western Scottish location and Atlantic exposure explain much of this difference.

At the same time, Glasgow is not consistently colder. Its annual temperature averages are extremely close to Edinburgh’s. Edinburgh also records slightly more air-frost days and a higher annual average wind speed at the comparison stations.

The practical conclusion is straightforward.

People living in or visiting Glasgow should expect more frequent rain across the year, particularly during autumn and winter. People in Edinburgh experience a considerably drier climate overall, although rain remains a normal feature of Scottish weather.

The phrase “Glasgow weather is worse than Edinburgh weather all year round” is therefore too broad.

A scientifically accurate statement is stronger and more useful: Glasgow is substantially wetter than Edinburgh throughout the year, while the two cities have broadly similar temperatures and several smaller differences in sunshine, frost and wind.

That distinction explains both Glasgow’s wet-weather reputation and the actual climate record.
