Boca del Rio 1 (Sama Coast)

Boca del Rio 1 is a low-profile point break on the Sama Coast that is described as consistent year-round for surfing, with both left and right-hand options. It’s generally best at high tide, though it can work across the tidal range. Southwest swell is the primary swell direction for the break. Line conditions are reported to be cleanest early in the morning when winds are lighter, before the daytime sea-breeze/thermal build can make the surface choppier in the afternoon. The spot is also noted for seasonal variability: August is identified as the best month, and winter periods are associated with larger, more powerful surf. Surfing here comes with significant natural hazards. Multiple sources highlight strong currents (including rip/river mouth currents) and rocky bottom conditions with submerged rocks. Very large winter waves are also flagged as a major risk, alongside rare but critical geohazard concerns (earthquakes and tsunamis). Visitors should plan to be self-sufficient and treat the water conditions with caution, especially around the river mouth after heavy inland rains. Despite the risks, the lineup is described as uncrowded for surfing, with relatively few surfers even on good days. On-site services are limited: lifeguards are seasonal, formal rescue is limited, and emergency services are about 50 km away in Tacna—so preparedness matters.
