Situated at the heart of Mediterranean Europe, the Principality of Monaco enjoys a particularly mild climate, with more than 300 days of sunshine per year. In winter, temperatures average between 48 to 58 degrees Fahrenheit with sunny days and cool nights. In the springtime, “Le Mistral” wind creates crystal clear skies with temperatures in the 50s-60s. Most summers are in the 80s with hot spells for a week or so in July and August. Sea breezes cool down the evenings. One of the loveliest times to be in Monaco is fall. With temperatures in the 60s to 70s, people are still sun tanning on the beach until mid-October.
