The best time to visit France is in spring (April-May), summer (June-August), or autumn (September-October). Spring is pleasant across the country, with fewer crowds and temperatures ranging from 55°F to 68°F. They can rise up to 84°F in summer, but aren’t too hot to stop you from exploring the cities, mountains, and countryside. Autumn is still warm, with temperatures between 61°F and 77°F, and vibrant landscapes as the leaves change color.
