Hemingway Days lands mid-July and fills the bars with look-alikes in cable-knit sweaters, which tells you everything about the local relationship with heat. Lobster mini-season at the end of the month turns the water into a parking lot of boats.
Expect about 7 days with real rain — enough to notice, not enough to plan around. Full tropical humidity: mornings are your friend, and shade is currency. about 18 afternoons top 90°.
Can you swim?
The ocean runs about 89° — bath-warm.
