Cardiff Solar Eclipse 2026: On Wednesday, 12 August 2026, Cardiff will witness a spectacular deep partial solar eclipse, with 93.2% of the sun obscured by the moon. This marks the most significant solar blockage over British skies since 1999. The sky will not turn pitch black like a total eclipse. Instead, it will create an eerie, surreal, and metallic twilight. Here’s everything you need to know about Cardiff Solar Eclipse 2026, date, time, best place to watch, and more.
Cardiff Solar Eclipse 2026: Date
The 2026 solar eclipse in Cardiff will take place on Wednesday, 12 August 2026.
What is Solar Eclipse?
A solar eclipse is a celestial event that happens when the Moon passes directly between the Earth and the Sun. When this alignment occurs, the Moon blocks the Sun’s light from reaching Earth, casting a moving shadow across our planet.

As this celestial event takes place late in the evening, timing is critical to catching it before sunset. The eclipse progresses as follows:
-
6:13 PM BST – Partial eclipse begins as the moon first touches the edge of the sun.
-
7:13 PM BST – Maximum eclipse occurs, turning the daylight into a surreal, dim twilight.
-
8:04 PM BST – Partial eclipse ends just as the sun gets very low on the horizon.

The sun will sit low in the west-northwest sky (around 12 to 15 degrees above the horizon during peak); any buildings or low trees to your west will block the view. To ensure an unobstructed line of sight, you should head to elevated hills or coastal viewpoints:
-

Cardiff Solar Eclipse 2026: How to Watch Eclipse Safely
Cardiff is experiencing a partial eclipse and not a total eclipse; the sun will never be entirely covered. You must protect your eyes and plan your location wisely:
-
Use Eclipse Glasses: You must wear ISO 12312-2 certified eclipse glasses at all times when looking directly at the sun. Standard sunglasses, camera lenses, or binoculars without specialized filters will cause permanent eye damage.
-
Find an Obstructed Horizon: At the peak of the eclipse, the sun will sit low—only about 13 to 16 degrees above the west-northwest horizon. Find an elevated spot like a hilltop, a clear coastal view, or an open park facing west to avoid buildings or trees blocking your view.
-
Bonus Skywatching: The eclipse happens just hours before the peak of the annual Perseid meteor shower. If you stay out after dark in a rural area, you can catch shooting stars.

Cardiff Solar Eclipse 2026: Safety Instructions
You must never look directly at the sun during the Cardiff solar eclipse without specialized eye protection, as doing so will cause permanent, irreversible eye damage. As Cardiff will experience a partial eclipse (93.2% coverage), a sliver of intense, direct sunlight remains visible at all times, making it dangerous from start to finish.
