National Mall exposure
The Mall is broad and open, so heat, humidity, wind and showers can accumulate across a walking route; compare the full window before making it the day's spine.

Sample data - not a live forecastStart with the local dates.
Washington, D.C. is usually the better choice when the forecast gives a usable stretch around the Mall and its museums. Put the longest outdoor links in that window, then use museums or neighbourhoods when showers or heat build. Change the day before the city; a nearby alternative belongs only in a clear live comparison.
Washington, D.C. is the United States capital, and the National Mall is a large open civic landscape with long sightlines between major institutions. Heat, humidity, storms and exposed walking can dominate the Mall even when nearby interiors remain manageable. The city's strong museum concentration makes local timing especially valuable.

What changes the shape of a local day?
Summer shower timing
Summer heat and humidity can accompany thunderstorms in Washington. Keep the long outdoor links between Mall museums movable rather than committing the whole day to open ground.
Directions, not permanent winners.
Northern civic direction
Philadelphia offers another dense civic and historic city profile when the Mall window is poor; it may share regional rain, so compare the actual metrics.
River-facing direction
A river-facing outing changes the open-space balance but may share the same humid heat or showers. Compare wind and rain with a shorter Mall-and-museum plan.
