London to witness deep partial solar eclipse on 12 August 2026

Londoners will witness a deep partial solar eclipse on 12 August 2026, with the Moon obscuring roughly nine‑tenths of the Sun’s disc. The Standard reported that the event starts at 6:17 pm, peaks at 7:13 pm and finishes close to 8:06 pm. This marks the largest partial solar eclipse seen from the UK in more than twenty‑five years.

The Standard pointed to Greenwich Park as a top choice for eclipse watchers. The park lies in southeast London and hosts the Royal Observatory along the Prime Meridian line. Its open grasslands and elevated position give a clear westward view as the Sun lowers in the sky. The article noted that the observatory’s presence adds a sense of occasion, and the surrounding area often attracts a lively crowd eager to share the experience. It also mentioned that the park’s closeness to the River Thames provides extra open space and that the Royal Observatory frequently organises special viewing sessions with expert talks and safe‑viewing equipment on the day.

Other suggested spots

The Standard also listed several alternative locations across the city. Telegraph Hill, situated near Nunhead, offers a quieter east‑to‑west aspect for those who prefer fewer people and features a small community garden where locals often gather for informal picnics. Primrose Hill, part of Regent’s Park in north London, provides sweeping views over London Zoo and the wider cityscape and is a favoured spot for sunset gatherings. Parliament Hill on Hampstead Heath rises to ninety‑eight metres, delivering a panoramic outlook that includes landmarks such as St Paul’s Cathedral and the Gherkin, while its elevated position overlooks the Heath’s ponds and woodlands. Alexandra Palace sits on a high ridge between Muswell Hill and Wood Green; its elevation was used by the BBC for the first television transmissions in 1936 and now offers an unobstructed skyward view above the tree line, with the surrounding park containing a boating lake that can reflect the eclipsed Sun. Crystal Palace on the Norwood Ridge features open grass areas and the upper Italian terraces, allowing an uninterrupted look toward the western horizon where the eclipse reaches its peak, and the park’s dinosaur trail adds a family‑friendly attraction for visitors.

Safety advice

The Standard quoted the Royal Observatory’s warning that looking directly at the Sun without proper solar filters can cause permanent eye damage. The observatory advised using certified eclipse glasses that meet the ISO 12312‑2 standard or employing indirect methods such as a pinhole projector to cast the Sun’s image onto a surface. It also stressed that children must be supervised and that even during a deep partial eclipse the remaining sunlight remains hazardous. Additionally, the Royal Observatory reminded viewers to check that their eclipse glasses are free of scratches or damage before use and to avoid using regular sunglasses, smoked glass or unfiltered telescopes, as these do not provide adequate protection.

“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.”

What comes next

The Standard added that the Royal Observatory said it will be a sixty‑four year wait until 2090 for the next total solar eclipse visible from the United Kingdom. The article noted that this long gap makes the 2026 partial eclipse a valuable opportunity to witness a significant solar event without leaving the country. The observatory also remarked that the 2026 event allows observers to experience a deep partial eclipse while awaiting the rare totality due in six decades. It highlighted that the 2090 total eclipse is expected to be visible from parts of the UK such as Cornwall and the Channel Islands, encouraging people to mark their calendars for that future date.
