The climate of this small and really wonderfull country is Mediterranean subtropical. It means there is a long, rather dry, hot and sunny summer, especially on the plains, and warm and rainy winter when cyclones often sweep over the territory of San Marino. The hottest month in San Marino is August.

The Adriatic coast in winter is exposed to the north and north-east winds of the "bora", which reaches San Marino. This cold wind blows with gusts in the clear sky and cumulus clouds. Very often, it is dry, but sometimes a cyclonic, or black, "bora" descends on the republic, which causes snowfalls and cloudy weather. In the winter the northeasterly wind, called the "Greek", dominates on the territory of the republic. And breezes blow in San Marino in the summer, as well as almost on the whole Adriatic coast. Dry southern wind that called "sirocco", which brings from Africa dust and "red rains", and also, "ponente", don’t reach San Marino. Therefore, we can say that the climate of San Marino is more than comfortable.
