The best time to visit France is in the spring (April to June) or fall (September to November) when there are fewer tourists, lower prices, and moderate temperatures. The summer months can be hot, crowded, and expensive. The winter months are often grey, wet, and cold (though a great time to visit the museums of Paris).
January is the hottest month in France with an average temperature of 17°C (63°F) and the coldest is January at 17°C (63°F).
