Yirrell Beach is a quiet sandy stretch located in Hull, Massachusetts, tucked along the south shore of Boston Harbor where it opens toward the Atlantic. Facing west along its transect into the inner harbor, this spot picks up wind swell and occasional rogue energy that wraps around the surrounding peninsulas, producing small, mellow waves well-suited for beginners and longboarders. Its remote feel and limited access keep crowds thin, making it a laid-back escape for Massachusetts surfers looking for uncrowded fun on smaller swells.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Yirrell Beach is 1-2ft with a 3.8s swell period. Wind is SE at 1mph. Conditions are rated Poor - Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Yirrell Beach is 1-2ft, produced by a 1.7ft ESE wind swell swell at 4s, a 1.2ft 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 Yirrell Beach is Monday from 6 AM to 9 AM with 2ft waves, a 9.6s swell period, and conditions rated Fair - Good. Check the hourly forecast for updates as conditions can shift.

Our Yirrell 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).
