What Causes a Rainbow in London
A rainbow forms when sunlight is refracted and reflected inside raindrops. In London, this typically happens when the sun is low and rain is falling nearby, often in the late afternoon or early morning.
Where to See a Rainbow in London
Open parks, riverbanks, and elevated viewpoints offer the best chances to spot a rainbow in London. After a brief shower with clearing skies, look toward the part of the sky opposite the sun.
Best Conditions for a London Rainbow
Rainbows are most common in London during spring and summer, when frequent showers follow sunny spells. They can also appear when mist or spray combines with sunlight, such as near the Thames.
