The average maximum winter temperatures have values between 20 ° C and 18 ° C. The intermediate seasons have mild and pleasant temperatures throughout much of the state.

The rains are well distributed in every month of the year and quite intense. Along the coast there are annual average values varying between 1,100 mm and 1,350 mm, while in the interior the rainfall increases up to values between 1,700 mm and 1,900 mm in the Serra Gaúcha. In general, the rainiest months are the winter months between July and September. In the highest mountains in winter it is sometimes possible to see snow.
