Lake Maggiore usually enjoys a very mild climate in comparison with that of the surrounding inland areas. This is true in both winter and summer seasons. For example, in the month of January, the average temperature is about 2-3°C. During the night it may drop below zero, but not by much. Leaving the lake in the direction of the internal valleys, the average temperatures drop and the rains are heavier.

The climate is rather mild in summer too, with an average temperature of 22°C and maximum of about 32°C. Some summers are humid, with sporadic thunderstorms.

The same conditions are reflected in the water temperatures of the Verbano. The surface reaches 5-6°C in the winter and 22-23°C in the summer season.

The mild climate of Lake Maggiore is attributable to the particular topography of the territory, with mountains to the north, valleys and plains to the south, making the environment Mediterranean at times and favouring the cultivation of the typical produce of warmer countries. In fact, you will find citrus fruit, olives and tropical plants in some particularly sheltered localities.

As in the case of other large Alpine foothill basins, there are some typical winds and breezes blowing on Lake Maggiore that alternate during the course of the day. In the early morning the north wind, also known as the moscendrino, brings cold from the north, while later, usually in the afternoon, the south wind known as the inverna blows from the plain to the south toward the mountains. Other characteristic winds are the maggiore and the mergozzo, especially at night. These winds, that blow in a special way during the good season, give breathing a break on the hottest days, leaving the air particularly clean and allowing for the practice of many water sports in the lake waters, such as sailing and windsurf.
