The sunshine, short rain showers and clean air in the US state of Hawaii create some of the planet’s best conditions for viewing rainbows. A University of Hawaii professor calls the state the “rainbow capital of the world.”
Rainbows appear so often in Hawaii that they’ve become symbols of island life. Pictures of them can be found on buildings, the sides of public buses and on standard vehicle license plates. Sports teams at the University of Hawaii are named after rainbows.
Rainbows form when raindrops refract sunlight into a spectrum of colours. The brighter the sun, the clearer the rainbow.
Look for them when it is both sunny and rainy at the same time. They will appear opposite the sun. They will seem larger and higher in the sky in the early morning and late afternoon when the sun is lower on the horizon.
