Best Conditions

Swell Direction: The ideal swell direction is WNW (300°), with workable conditions from W to NW (280°–320°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Thor's Hammer (Todos Santos Island) needs a minimum of 3m / 10ft to start working and handles swells up to 9m / 30ft before conditions deteriorate. When it maxes out, expect powerful, heavy-water conditions.

Swell Period: Look for a swell period of at least 14 seconds, with 17 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the E (90°). The full offshore range spans ENE to ESE (60°–120°). 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 low to mid tide.
