August is one of Washington, D.C.'s busiest months: hot and wet, around 30°C / 86°F with rain on about 16 days, and Packed every day.
No — not if you want Washington, D.C. to yourself. Every one of August's 31 days in our window is Busy or Packed, and the typical day is Packed. It is crowded throughout. Expect around 30 °C by day, with rain on about 16 days. No week of August is meaningfully quieter — the typical day is Packed throughout; pick by day instead. For similar weather with fewer people, come in September or April. The crush is at the Air and Space and Natural History rotundas; the quiet is at the National Gallery and the art wing quiet.
In short, a hard sell — heavy crowds without the best of the weather.
Among the 12 months we forecast for Washington, D.C., August ranks 5th for crowd pressure.
