Costellos is a sheltered beach break on New Hampshire's Atlantic coast that catches swell wrapping around the rocky headlands of the region. The northwest-facing exposure means this spot works best with northeast swell and southwestern offshore winds, offering mellow, rolling waves ideal for learning and progression. This quiet New England beach break provides a peaceful alternative to more crowded New England surf zones, with consistent small to medium waves during fall and winter swells.
