Best Time to Visit
The best times to visit Washington D.C. are during Spring (March to May) and Fall (September to November) when temperatures are mild and the city showcases its seasonal beauty.
Spring (March-May) is famous for the National Cherry Blossom Festival, typically peaking in late March or early April. The weather is pleasantly mild, though occasional rain showers occur. This is one of the busiest tourist seasons.
Summer (June-August) brings hot and humid conditions with frequent afternoon thunderstorms. While this is peak tourist season, the heat and humidity can be challenging for outdoor sightseeing.
Fall (September-November) offers comfortable temperatures and beautiful fall foliage, particularly in October. The crowds thin out after Labor Day, making it an excellent time for visiting monuments and museums.
