What May feels like
May is when the outdoor tables come out for good and the rooftop bars along 14th Street start taking an hour's wait. Thunderstorms roll through in the afternoons, usually from the northwest, and clear in time for the evening.
Rain arrives about 7 days of the month, so keep one flexible day in your plans. Humidity stays comfortable; the air never feels heavy.
