Climate Overview
San Marino has a temperate continental climate influenced by its elevated position at 600-756 meters on Monte Titano. Summers are warm to hot (22-28°C) with low humidity thanks to the mountain altitude, making it more comfortable than the coastal Adriatic resorts below. Winters are cold with occasional snow on the mountain, and spring and autumn are pleasantly mild with spectacular visibility to the Adriatic and Apennines.
