Weather in Glasgow in April

A hard month. April is a hard month in Glasgow, and worth planning around. Highs sit at 10.8 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

April ranks 6 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.

This is persistent light rain rather than storms: 16 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Layers, and a genuinely waterproof outer — at 10.8 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 20.8 °C and the coldest night fell to -4.3 °C, and the wettest single day dropped 25 mm — roughly 33% of the month's rain in one day.

April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 116 mm against 27 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 76 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 87%, which at 10.8 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How April sits in the year

The month is on the way up: 3 °C warmer than March, and May adds another 3.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in April

14.1 hours of daylight, gaining 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.

April 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, 4 days less rain. Manchester is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: April works, with July the better month by 15 points if the dates can move. If they cannot, nothing here should stop you booking.
