Here's how the next 5 days are shaping up at Middles, Puerto Rico. Each day is rated based on breaking wave height, swell period, and wind — updated hourly from the latest NOAA GFS run.
Thu, Sep 3: 0–1ft, 4s period, rated Very Poor. Not the most exciting day — 0-1ft and very poor conditions with strong ENE wind at 17mph.

Middles is one of the best surfing spots in Puerto Rico, a fast, barreling right-hander over rocky reef that has hosted the Rip Curl Pro Search and Corona Pro Surf Competition. Located behind the dunes north of Isabela, the wave is powerful and demanding, producing world-class barrels on N to NW swells. The exposed north-facing reef picks up virtually any Atlantic swell, making it one of the most consistent quality waves on the island.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Middles is 0-1ft with a 4s swell period. Wind is ENE at 17mph. 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 Middles is 0-1ft, produced by a 1.2ft ENE wind swell swell at 4s, a 0.6ft NNE secondary swell at 10s, a 0.6ft ENE wind swell swell at 7s. 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 Middles is Saturday from 6 AM to 9 AM with 2ft waves, a 7.5s swell period, and conditions rated Poor. Check the hourly forecast for updates as conditions can shift.
Middles 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 Middles. 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 Middles include rocky reef, strong currents, powerful waves, sea urchins, localism. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Middles 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).
