The UK is set to experience its most significant solar eclipse since 1999 on Wednesday, August 12, 2026. While not a total eclipse for London, the capital will witness a deep partial eclipse, with the moon covering approximately 90 to 96 percent of the sun. This is the greatest coverage seen from the UK and Ireland in over two decades, making it a must-see event for skywatchers.
In London, the eclipse will begin at 6:17 PM, reaching its maximum at 7:12 PM, when the moon covers the largest portion of the sun. The celestial show will conclude by 8:06 PM as the moon moves away. Clear skies are essential for viewing, so checking the weather forecast ahead of time is recommended.
Best Vantage Points in London
To get the best view, head to high vantage points with an unobstructed view of the western horizon, where the sun will be setting. Popular spots include Primrose Hill, which is expected to draw large crowds, so arriving early is advised. Parliament Hill in northwest London offers a panoramic view, allowing you to see landmarks like the Shard, St Paul's Cathedral, and the Gherkin while watching the eclipse.
The Royal Observatory Greenwich is hosting a viewing session with the Flamsteed Astronomy Society, with normal admission fees applying. Alternatively, Greenwich Park provides free open spaces for viewing. For those seeking a more organized experience, several venues are hosting eclipse viewing parties.
Eclipse Viewing Parties and Events
Horizon 22, located on the 58th floor of 22 Bishopsgate, is throwing an eclipse party with tickets at £25 for adults and £15 for kids, including a glass of bubbly or a soft drink. Kioku by Endo at the OWO will provide certified eclipse viewing glasses to all guests dining on August 12, with a terrace overlooking the Thames.
ZipWorld at the ArcelorMittal Orbit in Stratford offers two eclipse experiences: one with a planetarium show, expert talk, and a ride down the tube slide; the other includes an expert talk and access to the viewing platform. City Cruises London is also offering an evening cruise with drinks, canapés, and live entertainment to enjoy the eclipse from the water.
Safety First: How to Watch Without Damaging Your Eyes
Looking directly at the sun during an eclipse can cause serious eye damage, and regular sunglasses are not sufficient. To view the eclipse safely, you can create a pinhole projector to project the sun's image onto a surface, or use special solar eclipse glasses with a silver filter that blocks 99.99 percent of visible light and reduces harmful UV and infrared radiation.
Ensure any glasses you purchase are ISO 12312-2 certified, as many online options may not meet safety standards. Reputable camera or astronomy shops, such as the Royal Observatory Greenwich shop or Jessops, are good places to buy them, but they may sell out quickly.
Photographing the Eclipse with a Smartphone
If you want to capture the moment, protect your phone's camera with a solar filter, such as the ISO 12312-2 certified Solar Snap, or simply place a pair of eclipse glasses over the lens. This prevents damage to the camera sensor.
When Is the Next Solar Eclipse in London?
After August 2026, the British Isles will not see a full solar eclipse until September 23, 2090, a 64-year wait. So mark your calendars for August 12 and make the most of this rare celestial event.
