The Paris basin lies midway between Brittany and Alsace, and is affected by the climates of both. The Île de France region records the nation's lowest annual precipitation, but rainfall patterns are erratic; you're just as likely to be caught in a heavy spring shower or an autumn downpour as in a sudden summer cloudburst. Paris' average yearly temperature is 12°C (54°F) (3°C/37°F in January, 19°C/66°F in July), but the mercury sometimes drops below zero in winter and can climb to the mid-30s (high-80s/low-90s Fahrenheit) or higher in the middle of summer.
