Best Conditions

Swell Direction: The ideal swell direction is SSW (202°), with workable conditions from SSE to WSW (157°–247°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Prainha needs a minimum of 0.9m / 3ft to start working and handles swells up to 3m / 10ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 10 seconds, with 14 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the NW (315°). The full offshore range spans W to N (270°–360°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for early morning dawn patrol sessions.

Tide: This spot works best at all tides.
