What September feels like
September is the last easy month — the Maid of the Mist and the Cave of the Winds decks are both still operating, and the coach tours drop off sharply after Labor Day. Evenings cool fast, so bring more than the poncho they hand you.
Expect about 6 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
