What August feels like
Cherry harvest gives way to apples and the roadside stands are at their best of the year. Al Johnson's in Sister Bay still has goats on the roof and a wait to match, the harbors are full, and the outdoor shows in Peninsula State Park sell out.
Expect about 6 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The lake runs about 72° — comfortable for swimming.
