Best Conditions

Swell Direction: The ideal swell direction is WNW (300°), with workable conditions from W to NNW (270°–330°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Clachtoll needs a minimum of 1m / 3ft to start working and handles swells up to 3m / 10ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 8 seconds, with 12 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the SE (135°). The full offshore range spans E to S (100°–170°). 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 tide.

When to Go

Secondary Season: A secondary window opens March, April, May (Mar–May). While not as consistent, patient surfers can still score quality sessions during this period.

Water Temperature: Expect water temperatures around 10°C / 50°F. A 4/3mm or 5/4mm wetsuit is essential, with boots and gloves for extended sessions.
