📍 Local Knowledge

Costellos in New Hampshire is an exposed reef break with inconsistent surf and no clear seasonal pattern. It works best with southeast swells and offshore winds from the west. This left-hand reef break performs best around high tide. It’s a popular spot that can get crowded. Hazards include rocks and pollution. The best time for consistent, clean waves is during summer, particularly in August.
