What to expect in each part of the year.
Items
Spring (Cherry blossom season is D.C.'s most celebrated event. The Tidal Basin blossoms typically peak during the last week of March through the first week of April. Book accommodations 3–4 months ahead for festival week.), Summer (Busiest tourist season but very hot and humid. Free outdoor concerts, festivals, and July 4th celebrations. Plan outdoor activities for early morning and evening. Museums offer cool respite from the heat.), Fall (Second-best season. October is ideal with crisp air and fall foliage in Rock Creek Park. The Marine Corps Marathon in late October brings thousands of runners to the Mall area.), Winter (Quietest season. Hotel rates drop significantly. The museums are never crowded. Occasional snow and ice can disrupt Metro service. Pack layers for temperatures that can drop below freezing.)
