What June feels like
The Lilac Festival runs for ten days in the middle of the month and is the island's own favorite event; some of these bushes are well over a century old and the scent carries down the whole street. Book far ahead, because this is when the island fills without quite feeling like high summer yet.
Expect about 6 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 58° — cold — a quick dip takes resolve.
