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.

August: High Summer Action

August holds the 1.1m average with a 12.9s period. SSW swell remains dominant (96.5%), but 58.3% now falls in the 1-1.5m range – the highest percentage of the year. A full 3.5% reaches 1.5-2m, and 0.1% goes over 2.5m. Wind is ideal 76% of the time, with WNW (19.5%) and W (14.2%) providing a reliable offshore flow. Expect pumping, long-period waves that are a blast on a shortboard or step-up.
