Weather in Glasgow in October

United Kingdom · 20-year averages, October

A hard month. October is a hard month in Glasgow, and worth planning around. You should expect rain on 20 days of the month, which is more days wet than dry.

October ranks 7 of 12 in Glasgow: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain on 20 of the month's 31 days, 4 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Layers, and a genuinely waterproof outer — at 12.1 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 18.7 °C and the coldest night fell to -1.2 °C, and the wettest single day dropped 39 mm — roughly 27% of the month's rain in one day.

October is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest October on record still delivered 210 mm against 40 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 143 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 92%, which at 12.1 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How October sits in the year

The month is on the way down: 3.4 °C cooler than September, with November dropping another 3.6 °C. The first week and the last are not the same trip.

Daylight in October

10.6 hours of daylight, losing 2.3 hours across the month. That is between Glasgow's extremes of 17.5 and 7 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 16.1 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

October in Glasgow versus nearby

If Glasgow is one option among several, the nearby comparison is worth making. Edinburgh is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Manchester is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: October is a compromise. July is 19 points better and is what Glasgow is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
