The climate is Mediterranean. The average monthly temperatures are at their lowest in January (1°/2°C) and peak in July/August (26°/28°C).
The proximity to the sea increases the level of humidity in the winter and, to a lesser extent, in the summer. For the same reason, Ancona has medium-strength winds throughout the year with one of the strongest being the Bora, a cold, dry wind blowing in violent gusts, especially in the winter.
Other winds are the warm Scirocco and the Maestral, which usually bring good weather. The rainiest months are September and October.
