What May feels like
The rain arrives mostly as big evening thunderstorms that clear by morning and leave everything steaming. Forest Park is at its most extravagantly green right now, and the Tower Grove farmers market finally gets properly good.
Rain arrives about 8 days of the month, so keep one flexible day in your plans. Humidity stays comfortable; the air never feels heavy.
