UK and Europe witness rare solar eclipse; totality visible in Spain, Iceland, Greenland
A significant solar eclipse crosses the UK and western Europe on 12 August 2026, with 88–96% sun coverage in the UK and totality visible in Spain, Iceland, and Greenland—the first total eclipse in central or western Europe since 1999. Safe viewing requires certified eclipse glasses or indirect viewing methods, with clearer conditions expected in southern UK regions.

A significant solar eclipse will occur on 12 August 2026, with the UK and western Europe experiencing substantial partial coverage while several regions witness totality. In the UK, between 88% and 96% of the sun will be obscured by the moon, varying by location. Plymouth, Cardiff, and Belfast will see the highest coverage at 95%, 93.2%, and 93.1% respectively, while Edinburgh and Newcastle will experience around 90% coverage. The eclipse will begin around 18:08 to 18:19 BST depending on location, with peak coverage occurring approximately one hour later and the event concluding around 20:15 BST.
This marks the first time since 1999 that the UK will experience such substantial solar coverage, and the next comparable eclipse will not occur until 2081. Meanwhile, observers in Greenland, Iceland, Portugal, and northern Spain will witness a total eclipse lasting up to two minutes and 18 seconds—the first total eclipse visible from central or western Europe since 1999. Astronomers note the rarity of the event's extent: while solar eclipses occur almost yearly globally, the high coverage across western Europe is particularly uncommon.
For safe viewing, observers must use certified eclipse glasses bearing the ISO 12312-2 or ISO 12312-2:2015 certification, as regular sunglasses provide insufficient protection. The Royal College of Ophthalmologists documented approximately 70 vision-related cases following the 1999 eclipse. Alternative safe viewing methods include solar telescopes, pinhole projectors made from household items, or indirect projection techniques using colanders or tree foliage. Live streaming will also be available through the Royal Observatory Greenwich.
Experts recommend elevated locations with clear western horizons, as the sun will be low in the sky during the eclipse. Timing varies across the UK, with Edinburgh and Glasgow starting around 18:08 BST and Cornwall beginning near 18:18 BST. Weather conditions favour clearer skies in southern and eastern regions, with higher cloud risk in Scotland and Northern Ireland. Astronomers suggest checking weather forecasts closer to the date and conducting location reconnaissance beforehand, as cloud cover may partially or entirely obscure the event.
Why This Matters
On 12 August 2026, a solar eclipse will reduce daylight across the UK and western Europe, with 88–96% sun obscuration in the UK and totality in Spain, Iceland, and Greenland lasting up to 2 minutes 18 seconds. This is the first total eclipse visible from central or western Europe since 1999; the next comparable event will not occur until 2081. Safe viewing requires certified ISO 12312-2 eclipse glasses; the Royal College of Ophthalmologists documented approximately 70 vision-related cases from the 1999 eclipse. Public observatories, including the Royal Observatory Greenwich, will provide live streaming. Weather conditions, cloud cover, and geographic location will determine visibility quality across regions.
