Though Italy has a predominantly Mediterranean climate, Milan's winters (December-February) are certainly brisk, with lows below freezing. Still, mountains shield the city from the worst of the Northern European winter.
Summer (May-Sept) can be hot and muggy. In August, most of the city heads to the beaches to escape the 30°C-plus (86°F-plus) heat; the rest are in Milan's many gardens and parks.
