Stargazing in London, UK

London sits under some of the heaviest light pollution in Europe, with Bortle 8–9 skies across most of the city. Despite this, the Moon, planets, and bright doubles like Albireo remain rewarding targets — and the ISS is spectacular against the orange glow. For darker skies, head an hour south to the South Downs National Park (a designated Dark Sky Reserve) or north-west to the Chilterns. London's maritime climate means clear spells are common between frontal systems, particularly in late spring and autumn anticyclones. Plenty of Londoners just want to know what the London night sky looks like tonight — ClearSkys turns the cloud, moon and wind data into a single hourly score so you can see at a glance whether tonight's sky is worth stepping out for.
