Is Summer Over

For most practical purposes, summer is not over in the UK. Meteorological summer ends on 31 August, but astronomical summer continues until the autumn equinox on 22 September 2026, meaning you can still expect warm spells and the possibility of a late heatwave.

When does summer officially end in the UK?

There are two definitions. Meteorological summer (June, July, August) ends on 31 August, which is why many forecasts refer to September as autumn. Astronomical summer runs from the summer solstice (around 21 June) to the autumn equinox (around 22 September). For weather planning, the Met Office uses the meteorological calendar, so by that measure summer is over on 1 September. However, warm weather often persists into September, and the 90-day weather forecast UK models suggest above-average temperatures could continue into early autumn.

Will there be another heatwave in 2026?

It is still possible. The question “when is the next heatwave uk 2026” depends on high-pressure systems building from the south. Late August and early September can bring settled, warm conditions, especially in southern England. While no major heatwave is currently forecast, the answer to “when is the next heatwave in the uk” remains: keep an eye on the 10-day forecast for any sudden shifts. For those asking “will summer 2026 be hot uk”, the season has been mixed so far, but a late surge is not ruled out.

Is summer over yet? (The cultural question)

The phrase “is summer over yet” gained pop-culture traction from the Zara Larsson song, but in practical UK terms, the answer depends on where you live. In Scotland and northern England, summer conditions often fade by late August, while southern regions can enjoy warm, settled weather into mid-September.
