Overview
- The 2026 astronomical summer solstice is confirmed for Sunday, June 21, with the exact moment in the UK at 09:24 BST, and it marks the Northern Hemisphere's longest day and the start of astronomical summer.
- English Heritage will permit public access on the night of June 20 into the morning of June 21 and will provide a free YouTube livestream of the sunrise and sunset for remote viewers.
- Organisers warn of heavy traffic and sold-out parking for Stonehenge, and visitors are being encouraged to use public transport because local car spaces are limited.
- Local groups and sites are hosting alternative activities such as dawn yoga in Scarborough and guided walks in the Yorkshire Dales, and places at lower latitudes like Phoenix will see much shorter daylengths (about 14 hours 22 minutes).
- The solstice happens because Earth’s roughly 23.5° axial tilt points the Northern Hemisphere most directly toward the Sun, and people have marked the moment for millennia with gatherings at aligned sites such as Stonehenge.
