Playa Matapalo - surf spot statistics

Best Surf Season (May - October)

As the Intertropical Convergence Zone (ITCZ) shifts northward through late spring, the southern hemisphere begins to flex its muscles. This is the prime time for Playa Matapalo, as powerful, long-period SSW groundswells pulse up the Pacific coast. Average wave heights climb to 1.1m with periods consistently in the 13-14s range, delivering solid, rippable waves. September leads the pack with an 81% offshore wind frequency, as the trade winds weaken and the sea breeze pattern takes over. While the dominant swell direction (SSW) isn't ideal for this east-southeast-facing beach, a strong S out of the Pacific can wrap in with surprising punch. The reliable offshore winds from the WNW and NW groom the face, creating clean, glassy conditions. This is the window for your Costa Rica surf trip.

Fair Surf Season (November - April)

During these months, the ITCZ resides further south, and Southern Hemi swell becomes less frequent. Average wave heights drop slightly to 0.7-1.0m, but periods remain respectable (12-14s). The wind continues to favor the W to NW sectors, providing offshore sessions on many days. However, the swell is smaller and more intermittent. November and April see a mix of SW and SSW swell with occasional fun-size waves in the 0.5-1.5m range. This season is more about groveling on a log or fish, but the consistent offshore winds still make it worthwhile for the patient surfer.

Low Surf Season (December - March)

The heart of the northern winter sees the smallest average wave heights at Playa Matapalo, hovering around 0.7-0.8m. Despite the long periods (12-13s), the lack of significant swell energy means many days are too small for even a longboard. The strong trades are absent, and while offshore winds remain common (65-75% ideal), the swell simply isn't there. Only a few decent SSW pulses break the monotony. This is the low season for surf – a time of flat spells and micro waves, best reserved for sightseeing or looking for a rare east swell from distant systems in the Caribbean.

April: Building Swell

April marks the beginning of the upswell season. Average wave height climbs to 0.9m, period reaches 14.1s, and the percentage of 1-1.5m waves jumps to 32.8%. The SSW direction still dominates (99.7%), but these are powerful, long-period pulses that can stand up nicely on the points. Wind is ideal 66% of the time, with WNW (14.9%) and W (10.1%) offering clean conditions. Sets in the 1.5-2m range appear 0.6% of the time – a sign of things to come.
