Weather in Glasgow in June

United Kingdom · 20-year averages, June

Shoulder season. June is shoulder season in Glasgow — cheaper, quieter, and a genuine gamble. You should expect rain on 20 days of the month, which is more days wet than dry.

June ranks 3 of 12 in Glasgow. Only July scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 20 of the month's 30 days, 3 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. Pack for 16.5 °C days and 9.7 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest June day reached 27.7 °C and the coldest night fell to 3.6 °C, and the wettest single day dropped 30 mm — roughly 28% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 173 mm against 55 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 106 mm average is a reasonable planning figure, not a promise.

Wind is light at 11.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 85%, high enough to notice on the warm days without dominating them.

How June sits in the year

Temperatures hold steady either side: 13.9 °C in May, 16.5 here, 18 in July. Nothing about the timing within the month matters much.

Daylight in June

June is at or near the longest days of Glasgow's year: 17.5 hours of daylight, gaining 0.4 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

June 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 a better bet in June — within a degree on temperature, 5 days less rain.

So: June is effectively as good as it gets here — 5 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
