What to pack

What August feels like

August is when the water reaches the temperature people were expecting back in June, and it is also when Thunder Over the Boardwalk brings the air show and a crowd that fills the beach end to end. Thunderstorms build over the mainland and drift out over the island in the late afternoon.

Expect about 6 days with real rain — enough to notice, not enough to plan around. It’s sticky — light fabrics and an afternoon break earn their keep. about 6 afternoons top 90°.

Can you swim?

The ocean runs about 72° — comfortable for swimming.
