Solar eclipses will return to the UK on Wednesday August 12 2026, when a deep partial eclipse will cover around 90 percent of the Sun. Viewers in Cornwall and Spectators in Pembrokeshire will see the strongest effect, while People in Edinburgh and Glasgow will see it earlier and People in Truro later.
Britain will not get the full eclipse. It will get the largest solar eclipse since the total eclipse of 1999, and the event is described as the most significant eclipse seen in the UK in almost 30 years.
August 2026 solar eclipse
Royal Museums Greenwich says the eclipse maximum times for each region are available, but the figures themselves are not included here. That leaves the practical question for People in the UK: the date is fixed, the coverage is known, and the exact peak moment depends on location.
The key distinction is simple. A total solar eclipse happens when the Moon passes between the Earth and the Sun. The August 2026 solar eclipse in the UK will be partial rather than total, so the Sun will be covered but not fully obscured.
Cornwall and Pembrokeshire
The southwest will get the deepest view. Viewers in Cornwall will see roughly 95 percent of the Sun covered, and Spectators in Pembrokeshire will see around 94 percent. Those figures place both areas above the UK average of around 90 percent.
People in Edinburgh and Glasgow will be among the first to witness the partial eclipse, while People in Truro will be among the last. For anyone planning around the event, the regional timing is the detail to watch, not the national average.

The source says total solar eclipses happen every 18 months or so, but a given location may wait 366 to 400 years to see one. That is why the August 2026 solar eclipse is notable even though it is not total in Britain.
For readers in the UK and Ireland, the practical next step is to check the regional maximum time once those figures are available through Royal Museums Greenwich and plan around the local peak, especially in Cornwall and Pembrokeshire.
