What June feels like
The beaches are open and busy, but the lake takes until deep summer to warm up; June swimming is a brief, shrieking business. The payoff is the light — evenings at North Avenue Beach run absurdly long, and the Grant Park festival season gets underway.
Expect about 7 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
Can you swim?
The lake runs about 63° — cold — a quick dip takes resolve.
