A rare triple rainbow colored the skies of the eastern Athens neighborhood of Goudi on Monday afternoon.

An Athenian took a picture of the phenomenon and sent it over to the Director of National Meteorological Center, Theodoros Kolydas, who shared the photo along with a brief description on X.

Kolydas explained in his post, in Greek, that “rainbows are an optical phenomenon created by the refraction and reflection of light in water droplets. For the phenomenon to occur, we need both rain and sunlight present simultaneously. The sun must be behind us, and the raindrops in front of us. If someone is at the top of a mountain or a tall building, they will be able to see the entire circle of the rainbow.”
