Climate

Portorož, with its sub-Mediterranean climate, is one of the warmest areas in Slovenia. There are many sunny days. The yearly average of the them amounts to 2,346 hours.

Precipitation is scarce and range between 1,000 and 1,100 mm per year. The mild winters, with temperatures very rarely below zero, are characteristic, as well as the not too hot summers. Due to all this, visitors not able to stand the severe heat of the southern parts of the Mediterranean in summer are our most frequent guests.
