The local and periodical (seasonal) winds also help to maintain a favorable climate. Among them, the most distinct are the local winds "Jugo" (south-east wind) and "Bura" (north-east wind), which show up during the entire year, but especially well marked during winter, when their bio-climatic activity is at it's peak. In the early spring and summer, the most characteristic wind is "Maestral" which has important thermo regulation activity, because as it is a sea wind, it brings a favorable coolness. "Maestral" is replaced by the night breeze from the north ("Burin"), which cools the overheated dry land. Rainfall on the this area also has Mediterranean characteristics. It amounts to only 809 mm (32 in) yearly, but it is favorably dispersed, so that Spring and especially Summer is mostly dry, while moderate rains fall in Fall and Winter season. Snow is an exceptionally rare phenomenon.
