Weather in Washington, DC

Best time to visit

Washington DC has a temperate climate with four seasons. It’s best to visit in spring, early summer and autumn when the oppressive heat and humidity of the summer has abated. Moderate winters are not unknown with more rain than snow. This is when the hotels are at their cheapest. The busiest time for the city is from March to June when the cherry blossom is in full bloom and the capital is bursting with families and school groups. Hotel rooms are at a premium, so it is essential to book in advance and be prepared to pay inflated prices.
