Overview
Cahuita is a stretch of black sand beach break inside Cahuita National Park, with a fun left-hand reef and point tucked into one end. That mix gives you rights and lefts in the same session, breaking over sand at the beach and reef and sand at the point. It is one of the better options on the Caribbean side of Costa Rica, a coast with real charm and a handful of quality waves, and a good call if you happen to be in the country during the Pacific's offseason. Sightseeing and surfing in one spot works nicely here.
When It Works
Winter is the season. Caribbean spots break best in the colder months, and Cahuita follows that pattern. Swell arrives from north through east-northeast, and the spot is usable from 1.5 m / 5 ft to 2.4 m / 8 ft, which lines up with the head-high to overhead range it tends to deliver. The waves are decent when it all comes together, with a nice variety of beach break peaks alongside the left point.
Wind and Tide
Look for west-southwest offshore wind, with a workable window running from southwest to west. Tide is flexible here, and it works through low, mid, and high, though a rising tide is generally the better call. If you want to narrow it down, the beach break favours high tide while the left point prefers mid to low.
Local Tips
An intermediate level of surfing will get you a lot out of this place, and a shortboard or funboard both suit the waves. Expect a moderately busy lineup, mostly concentrated at the left point, which draws locals and can turn competitive. The beach break stays much quieter if you want space. The vibe is reserved but the locals are friendly, as they tend to be across Costa Rica. Watch the rip, which can run a bit, and keep the reef in mind at the point. Water quality is not perfect either, with some sewage issues along this stretch.
Access
Park at the entrance to Cahuita National Park or on the side of the main beach road, then walk down to the black sand beach.
