What May feels like
May is the month the city moves onto the sidewalk: the Broad Street Run takes ten miles of Broad on the first Sunday and the beer gardens open all over town. Spruce Street Harbor Park opens on the Delaware and the hammocks get claimed by noon.
Expect about 6 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
