When Does Summer Start in the UK?
The UK uses two definitions. One is based on the weather calendar and the other is based on the Sun. Both are correct, so you will often see two different dates online.
Meteorological Summer: 1 June 2027
The Met Office counts summer as June, July and August. It uses whole calendar months so that weather records can be compared fairly from one year to the next. Meteorological summer runs from 1 June to 31 August 2027, which is 92 days.
Length of each meteorological season (days)
- Spring (Mar–May): 92 days
- Summer (Jun–Aug): 92 days
- Autumn (Sep–Nov): 91 days
- Winter (Dec–Feb): 90 days
Astronomical Summer: 21 June 2027
Astronomical seasons follow Earth’s tilt and its path around the Sun. Summer begins at the June solstice, which in 2027 falls on Monday 21 June at 3.11pm BST (2.11pm UTC), according to the Royal Observatory Greenwich. The exact moment moves slightly each year, so the date can change by a day. This season ends at the September equinox, around 23 September 2027.
Meteorological vs Astronomical Summer: What’s the Difference?
| Difference | Meteorological summer | Astronomical summer |
|---|---|---|
| Start date (2027) | 1 June | 21 June, 3.11pm BST |
| End date (2027) | 31 August | Around 23 September |
| Based on | Calendar months | Earth’s position and tilt |
| Mainly used for | Weather records and forecasts | Solstice and “longest day” dates |
| Days from 3 Nov 2026 | 210 | 230 |
For a UK reader, 1 June is the best everyday answer because it matches how the Met Office reports the season.
When Is the Summer Solstice 2027?
The summer solstice is on Monday 21 June 2027. It is the longest day of the year in the Northern Hemisphere because the North Pole is tilted as far towards the Sun as it gets. After this date the days slowly get shorter until the December solstice.
In London, the Sun rises at about 4.40am and sets at about 9.21pm, giving roughly 16 hours and 40 minutes of daylight. Those long, light evenings are perfect for simple outdoor games for kids with no equipment.
London on 21 June 2027

When Is Summer in Australia?
The seasons are reversed in the Southern Hemisphere, so Australia’s summer is December to February, according to the Australian Bureau of Meteorology. Earth’s tilt means that when the UK leans towards the Sun, Australia leans away. Right now the UK is heading into winter, while Australia is about 28 days from the start of its summer.
