Located along the northern coast of Puerto Rico near the historic capital city, San Juan offers reef-driven waves that light up during the North Atlantic swell season from November through March. The NNW-facing exposure at these coordinates positions the break perfectly to receive groundswells generated by winter storms tracking across the North Atlantic, producing punchy, fast-breaking waves with good shape. This spot blends an urban surf culture with surprisingly quality surf, making it a convenient session for both locals and traveling surfers exploring Puerto Rico's vibrant north shore.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at San Juan is Flat with a 8.05s swell period. Wind is ESE at 14mph and 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 San Juan is Flat, produced by a 0.3ft NNE primary swell at 9s, a 2.8ft ENE wind swell 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 San Juan is Saturday from 6 AM to 9 AM with 1ft waves, a 4.55s swell period, and conditions rated Very Poor. Check the hourly forecast for updates as conditions can shift.
San Juan works best with a N swell and SE 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 San Juan. 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.
