U.S. Capitol · Washington, DC. Data: exact sun position; climate normals from historical weather; live forecast on the interactive view.
The Capitol stands at the head of the National Mall on a rise of open ground, and the approach is almost all lawn and pavement. The grounds are broad and largely treeless near the building itself, so a summer walk up to it means time in full sun. Washington in July is warm and humid, with afternoon highs around 89°F, and the exposed plazas and the long open stretch of the Mall below give little cover during the hottest part of the day.
In high summer the sun rises around 5:55 AM and sets near 8:32 PM. By 3 PM it stands 61 degrees up and sits to the west-southwest at about a 240-degree bearing, high and strong over the open grounds. The building's great dome and its bulk throw shade to the northeast as the afternoon sun swings west-southwest, so the northeast side of the plaza and the steps holds shade earlier than the west-facing approach. The open lawns and the wide walkways of the Mall, though, sit in direct sun through most of the day.
Midday, with the sun high and to the south, is when the plazas and lawns are most exposed and the shade thinnest.
Washington's summer humidity is the real burden here, not the temperature alone. The muggy air near 89°F keeps sweat from cooling you, so the open Mall feels hotter than the number suggests, and there is little shade to rest in on the walk up to the building. Come in the morning, when the air is cooler and the eastern edges of the grounds still hold shade, or in the late afternoon as the sun drops and the building throws long shadows across the plaza. Carry water, wear a hat, and use the tree-lined margins rather than crossing the open lawns at midday.
