Hallows is a reef break located on the northwest coast of Puerto Rico, picking up south-southwest swells that wrap into the break with punchy, hollow sections. The SSW-facing exposure means it comes alive during winter groundswells generated in the South Atlantic, delivering fast, powerful waves over a sharp reef bottom. Its relatively secluded position and demanding conditions keep the lineup manageable for those willing to make the effort.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Hallows is 2-3ft with a 11.6s swell period. Wind is E at 10mph and 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 Hallows is 2-3ft, produced by a 1.7ft NE primary swell at 7s, a 1.4ft NE secondary swell at 12s, a 0.9ft NNW tertiary swell at 8s. 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 Hallows is Tuesday from 6 AM to 9 AM with 3ft waves, a 8.5s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
Hallows works best with a N swell and S 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 Hallows. 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 Hallows include shallow reef, sharp coral, strong currents, localism, rocks. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Hallows 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. See the forecast accuracy card above for per-spot and regional performance metrics.
