Sirmione is a four season climate with hot summers and mild winters. Spring and summer are the top tourist times to visit for those who want a golden, Italian tan. The summer temperatures remain steady in the 80s but the breeze off of the lake keeps the air comfortable.

Winter is quite mild but does get down to the 40s and 30s therefore, winter attire is necessary. But as in most locations of Italy, Christmas is a beautiful time to visit.

The main attraction however, is the Sirmione Spa and it is open year round. The world class spa has therapeutic treatments and thus visitors do come at all months. Those wishing to engage in more tourist type activities and who prefer the more lively season however, will enjoy downtown Sirmione best in late spring and through summer. June through September also sees many music festivities in the downtown square of Sirmione. July features the "Lake Festival" and September has a "Grape Festival". The summer also sees two market days, Friday and Monday, for tourists to benefit all the more. Check with hotels to find summer promotional rates and of course, off-season specials.
