The summer solstice in 2026 will occur on Sunday, June 21 at 9:24 am BST, marking the longest day and shortest night of the year in the United Kingdom. This astronomical event takes place when the northern hemisphere is tilted closest to the Sun, resulting in up to 18 hours of daylight in some parts of the UK, including London.
Although many people think of the solstice as lasting an entire day, it is actually a precise moment when the Sun appears at its highest position in the sky, creating the extended daylight that characterizes the event.
Stonehenge Celebrations
Stonehenge will host thousands of visitors for the traditional solstice celebration. The ancient site is aligned with the direction of the sunrise on the summer solstice, making it a significant location for marking this annual event.
English Heritage is allowing open access to Stonehenge from Saturday evening through Sunday morning. Sunrise is expected at around 4:52 am above the Heel Stone.
Parking has already sold out. Visitors are encouraged to use public transport where possible, as heavy car traffic is anticipated from Saturday afternoon, June 20.
Rituals and Significance
The occasion is celebrated by pagans, druids, and many others who gather for rituals symbolizing rebirth and the changing seasons.
Astronomical vs. Meteorological Summer
Astronomically, the summer solstice marks the beginning of summer. The Royal Museums of Greenwich explains: "The tilt of the Earth produces the seasons, including the changes in weather associated with them. When the northern hemisphere is tilted towards the Sun, it receives more direct sunlight and for a longer portion of the day, so the temperature increases. Similarly in winter, the reduction in sunlight hours and more glancing angle to the Sun means the air remains colder."
While the solstice marks the official start of astronomical summer, meteorological summer starts at the beginning of June due to the time it takes for the atmosphere and oceans to heat up, and runs until the last day of August.
