Since Korcula is an island, winds have an important role there. They influence its economic activities, and its connections with the mainland in particular, and they enable recreational and tourist activities. The two dominant winds blow from the E and SE (JUGO) and the W and NW (MAESTRAL). The winds of the South-West quadrant have the dominant role and the strongest physiological influence on the people and crops. They are most frequent in autumn and winter but also in early spring. Moisture is at its highest in the period and temperatures are consequently much higher. the most frequent wind in the summer period is the North-West wind known as the Korcula Maestral. It is particularly frequent and strong in the Peljesac channel, whereas it is almost absent on the open sea. The Maestral in the Korcula - Peljesac channel is favorable for the popular summer sport of wind surfing, because it enables high speeds and sailing around the whole of the Korcula archipelago. For this reason Croatian and international sailing and wind surfing competitions often take place in Korcula and Orebic.
The continental winds form only a small proportion of the total winds which blow over the island of Korcula and are limited in time, JUGO is predominant in winter, and the MAESTRAL in summer.
