What July feels like
The Sagamore and Bourne are the only way on, and a Friday afternoon in July is a lesson in patience — locals leave before noon or after nine. Once you're over, this is the least rainy run of the year and the sea finally stops being a dare.
Expect about 5 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 69° — brisk but swimmable.
