The UK is about to see its most complete solar eclipse since 1999, with the moon covering a huge portion of the sun’s light on 12 August.
While it won’t be a total blackout for most of the country, this dramatic partial eclipse will transform the daytime sky right across the UK, though exactly how much coverage you’ll see depends on where you’re standing. Whether you’re planning to step outside with safe viewing glasses or just want to catch the peak moment from your garden, a bit of preparation goes a long way.
Here’s everything worth knowing about timings, the best viewing spots, and how to safely watch the spectacle before the big moment arrives.
Most of the country will see a truly striking eclipse.
On 12 August, the moon will block a massive share of the sun’s light across the UK, marking the deepest coverage seen on these shores since the famous total eclipse back in 1999. London and the Home Counties can expect around 90% coverage, meaning almost the entire solar disc will disappear behind the moon at the absolute peak of the event.
If you’re further south or west, the view gets even better; the South West of England and parts of Wales are set to see around 95% coverage, making those regions the absolute prime locations in the whole country for watching the sky darken. However, even if you’re further north in Scotland or Northern Ireland, you’ll still get an incredible show with well over 80% coverage. Wherever you happen to be standing, an astronomical event of this scale is rare enough that it’s well worth stepping outside to catch a glimpse.
The whole event unfolds over roughly two hours.
You don’t need to worry about missing the whole thing in the blink of an eye, as the celestial show plays out over a generous two-hour window. The eclipse begins with what astronomers call “first contact,” the precise moment the moon’s edge first starts creeping in front of the sun, which will happen just after 6 p.m.
From that point, the sky will gradually dim as the moon bites further into the sun over the course of an hour. The dramatic moment of maximum coverage arrives just after 7 p.m., when the day will feel noticeably cooler and twilight-like, before the moon slowly glides away and the eclipse finishes entirely just after 8 p.m. Having such a wide timeframe means you can comfortably pop outside after work or dinner to take it all in without rushing.
Never look directly at the sun without proper protection.
While it’s easy to get caught up in the excitement, protecting your eyesight is the single most important thing to keep in mind. The UK Health Security Agency has issued a clear warning ahead of the event, reminding everyone that staring directly at the sun, even when 95% of it is covered, can cause severe, permanent eye damage in a matter of seconds. Because the sun’s harsh rays aren’t completely blocked, your eyes won’t naturally trigger a blink reflex, making it surprisingly easy to cause burn damage to your retinas without feeling it happen.
To watch safely, standard sunglasses simply won’t cut it. You’ll need actual eclipse glasses equipped with certified solar filters that block out harmful radiation. If you don’t want to buy special gear, you can easily set up a safe, indirect viewing method at home. Making a simple pinhole projector using two pieces of white card is a classic trick, or you can even grab a colander from the kitchen cupboard, hold it up to the sun, and watch dozens of tiny crescent-shaped shadows cast onto the ground beneath it.
You can watch online if the weather doesn’t cooperate.
As anyone living in Britain knows, mid-August is no guarantee of clear blue skies, and a heavy blanket of grey cloud could easily threaten to block out the view. If the weather decides not to play ball in your area, or if you’re stuck indoors working, you don’t have to miss out on the magic entirely.
The Royal Observatory in Greenwich will be running a live stream of the entire event online, tracking the moon’s progress using professional telescope equipment from clear vantage points. Having that digital backup option ready on your phone or laptop means you can still experience the grandeur of the eclipse, no matter what the unpredictable British weather decides to do overhead.
