London will experience its largest partial solar eclipse in 25 years this Wednesday, with several parks and hills offering prime viewing spots. The event will be the largest partial solar eclipse, when the moon moves to cover the sun, in over a quarter of a century to be witnessed in the UK.
It is estimated that around 90% of the sun will be obscured by the moon, triggering a rare and stunning natural phenomenon. According to Royal Museums Greenwich, which includes the Royal Observatory: "A solar eclipse occurs when the Earth, moon and sun align. The moon passes in front of the sun and blocks its light, casting a small shadow on Earth."
The observatory said it will be a 64-year wait until 2090 for the next total solar eclipse visible from the UK, meaning it is worth seizing the opportunity in 2026 to see a natural phenomenon. Just as was the case in 1999, Cornwall, which experienced a total eclipse 27 years ago, is forecast to be the best place in the UK to watch the eclipse. Spectators gathering in popular spots such as Land's End and The Lizard Peninsula are to be treated to 95% coverage.
Where to watch in London
For those wanting to watch, there are strict safety guidelines to follow when it comes to eyesight protection. The Royal Observatory states that a person should never look directly at the sun without the appropriate filters, providing information on how to watch it safely.
London's hills and open spaces will be the best places to watch the solar eclipse on Wednesday, August 12. The eclipse will begin at 6.17pm and the height of the eclipse is expected at 7.13pm. From London, it will last around 1 hour and 49 minutes until 8.06pm.
Here are some of the best vantage points in the capital.
Greenwich Park offers a unique perspective. With the Royal Observatory and the Prime Meridian line on one side and the view of the London skyline the other, this London beauty spot is sure to have not only a great view of the partial eclipse, but also a vibrant atmosphere to match. Situated in the south-east of the city, it should offer a wide vista as the sun comes down in the west.
For those in south-east London less fond of crowds, Telegraph Hill, situated near Nunhead, could prove the ideal place to set up camp on August 12. It still offers that east-to-west angle while being slightly further from the tourist hub of Greenwich.
Primrose Hill offers views over London Zoo and well beyond. Part of Regent's Park in north London, it is sure to be popular among those looking to catch a glimpse of the powerful solar display.
Parliament Hill rises to 98 metres and is one of London's highest natural points, offering panoramic views of the city skyline. Visitors to this part of Hampstead Heath on August 12 will be able to contrast man made brilliance with natural beauty as they take in the effect of the eclipse while also spotting St Paul's Cathedral, the Gherkin and other major London landmarks on the horizon.
Crystal Palace sits on the Norwood Ridge. Its high elevation will provide an open, elevated view toward the west where the eclipse will peak. The upper Italian terraces of the south London landmark and the open grass areas of its park should provide plenty of space to locate a spot to watch the sun and moon fusion without tall buildings blocking the view.
Safety reminders for viewers
Eye protection remains essential throughout the event. Regular sunglasses do not provide adequate protection. Certified eclipse glasses or solar viewers meeting the ISO 12312-2 standard are required for direct viewing. Indirect methods such as pinhole projectors offer a safe alternative for those without proper filters.
