Best Conditions

Swell Direction: The ideal swell direction is SSW (195°), with workable conditions from S to SSW (180°–210°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Serangan needs a minimum of 0.9m / 3ft to start working and handles swells up to 1.8m / 6ft 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 WNW (292°). The full offshore range spans W to NW (262°–322°). 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 mid to high tide. Optimal tide range is 0.7m–1.8m.
