Monte Solaro is also called "Acchiappanuvole" ("cloud catcher") after the thick blanket of fog which forms around the summit, especially at dawn, when the thermal difference between the sea and the rock is accentuated. The warmer, damper sea air condenses in a dense mist on the ground, the temperature of which has notably diminished during the night. Where its path is obstructed, the vapors rise upwards generating a characteristic crown of clouds. This phenomenon also occurs in the evening.
