Plan for the conditions

Expected seasonal weather

From June to early October, the Seacoast usually brings warm days, though onshore breezes keep the shore and the harbor cooler than inland, and it's often 5–10 degrees cooler on the water. Fog can roll in from the Gulf of Maine, and summer afternoons can bring thunderstorms. By October, mornings are crisp, afternoons are mild and the wind on the water feels cold. Spring is cool and changeable. These are seasonal expectations, not a forecast for your travel date; check the NWS forecast the evening before and the morning of your trip.

Admission and parking are separate. Check current conditions before departure.

A good day, in the bag.
