Playa Lagarto seasonal overview

Best Surf Season (May - November)

As the Intertropical Convergence Zone (ITCZ) shifts northward, the strong northerly trade winds that plague the winter months relax dramatically. This is when Playa Lagarto truly comes alive. The dominant wind flow turns westerly, providing clean offshore conditions for over 60% of the time. Swell energy is generated by powerful Southern Hemisphere storms, arriving as long-period SSW groundswell with average periods of 12-14 seconds. While the SSW direction isn't a perfect match for this East-Southeast facing beach, the long intervals wrap nicely into the bay, producing fun, rippable waves in the 1.0-1.5m range. The combination of offshore breeze and consistent pulse makes this the prime window for quality surf.

Fair Surf Season (April & December)

These transitional months offer a mixed bag. April marks the end of the northerly trades, with wind ideal percentages climbing to 35% as westerlies begin to appear. Swell remains consistent from the SSW, with periods averaging 13.7s – some of the longest of the year. December sees the opposite shift: the trades are rebuilding, with wind ideal at 48% as northerlies start to dominate. Swell direction becomes more mixed, with both SSW and northerly components from developing cold fronts. It can be good during breaks in the wind, but requires more patience to pick off a clean window.

Low Surf Season (January - March)

The first three months of the year are dominated by the relentless northerly trade winds. Expect strong winds from the N-NNE quadrant 50-60% of the time, creating choppy and messy onshore conditions. Swell sources are split between northerly windswell and occasional SSW pulses, with average periods between 9-12s. The northerly windswell brings short-period, sectiony waves that are tough to surf, while any SSW swell is often ruined by the cross/onshore flow. Ideal wind percentages bottom out at 14-20%. Surfable days are rare and usually require a break in the trades – a scenario more common during weak cold fronts or passing disturbances. Highly recommended to look elsewhere during this period.

Conditions at Playa Lagarto in December

December: Changing of the Guard

December is a transitional month as the northerly trade winds ramp up. Wind ideal drops to 48%, with N winds accounting for 43.5% of the total. Swell direction becomes more mixed: while SSW swell is still significant (38%), there is a growing contribution from northern directions (N, NNE, NNW) at over 25% combined. Wave periods average 10.3 seconds, reflecting shorter-period windswell. The surf quality becomes more inconsistent; you'll need to pick your days carefully. When a vigorous cold front dips south, it can bring a burst of NNE swell with decent period. The best windows occur when a passing system sets up light offshore W winds. Still, the consistent magic of the previous six months begins to fade.
