Jenness Beach offers accessible sandy beach breaks along New Hampshire's Atlantic coast, with a westerly-facing orientation that captures northeastern Atlantic swells and autumn storms. The sandy bottom provides forgiving waves ideal for beginners and intermediate surfers looking to practice their fundamentals in a relatively sheltered setting. This popular local break can get crowded during good conditions, but remains a reliable option for New England surfers seeking consistent beach break action without venturing too far offshore.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Jenness Beach is 1-2ft with a 4.4s swell period. Wind is NE at 4mph. Conditions are rated Very Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Jenness Beach is 1-2ft, produced by a 2.2ft SE wind swell swell at 4s, a 1.4ft ESE secondary swell at 9s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.
Based on the current 5-day forecast, the best window to surf Jenness Beach is Friday from 6 AM to 9 AM with 2ft waves, a 6.2s swell period, and conditions rated Fair - Good. Check the hourly forecast for updates as conditions can shift.
Jenness Beach works best with a NE swell and WNW winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.
Tide plays a big role at Jenness Beach. Mid tide works for most beach breaks, while reef and point breaks often prefer higher or lower stages. Use the tide chart above to line up your session with the swell peak.

Common hazards at Jenness Beach include rocky outcrops, strong shore break, cold water temperatures, occasional rip currents. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Jenness Beach forecast uses NOAA GFS and other weather models combined with spot-specific bathymetry to calculate breaking wave heights. Short-range (1-3 day) forecasts are most reliable; extended forecasts show general trends. We also verify our offshore swell predictions against NOAA buoy measurements daily — see our accuracy page for those swell-verification metrics (buoys measure open-water swell, not breaking surf size).
