Exact date sun will set after 10pm as summer begins tomorrow

Tomorrow, June 1, marks the start of meteorological summer for the UK and the rest of the Northern Hemisphere. According to the Met Office, meteorological summer will always begin on June 1 and end on August 31.

According to the Met Office, the meteorological seasons are each exactly three months long to "coincide with our Gregorian calendar, making it easier for meteorological observing and forecasting to compare seasonal and monthly statistics."

This differs from astronomical summer, which can change slightly year on year. The astronomical calendar's seasons are determined by the tilt of the Earth's axis in relation to its orbit around the sun. This calendar sees summer begin with the summer solstice, and end with the autumn equinox.

This year astronomical summer will run from June 21 - the longest day of the year - until September 22. From now until June 22, the days will continue to get longer, with parts of the UK about to experience some post-10pm sunsets.

According to forecasts, the first of these will take place on Saturday, June 7. This will be the case for County Fermanagh, one of the most western parts of Northern Ireland.

Those in Edinburgh can expect to wait a further eight days - until Sunday, June 15 - for the sun to set after 10pm. The latest sunset London will experience in 2025 will be at 9.22pm on Saturday, June 21, while for both Birmingham and Cardiff it will be 9.34pm on the same day.

Ness Point, which is the eastern most part of the UK, is expected to experience a sunset at 9.20pm on June 21.
