Gas Chambers - surf spot statistics

Best Surf Season (November - March)

During the winter months, the North Atlantic cranks up its fury, sending consistent swell trains that push into the 1.5m to 1.6m range with average periods around 10 seconds. While the dominant swell direction remains from the NE-ENE quadrant — far from ideal for this WSW-facing beach — the combination of larger, longer-period groundswell and frequent offshore winds from the E-ENE sets the stage for the most rideable surf of the year. Be ready for punchy, often hollow waves when the wind lines up just right, but don't expect the classic SW groundswell that would truly light up the lineup.

Fair Surf Season (April - May & September - October)

The shoulder months offer a moderate blend of conditions. Swell heights drop to 1.1-1.3m and periods hover around 9-10 seconds, still predominantly from the NE. With wind ideal surf time increasing to 54-67% of the month, these periods yield cleaner, more consistent sessions, though the lack of quality swell direction keeps the waves from reaching their true potential. Smaller days mix in with occasional fun-sized runners when an easterly fetch aligns.

Low Surf Season (June - August)

Summer slumps hard at Gas Chambers. Average swell heights bottom out at 1.0m with periods shortening to 6-7 seconds, resulting in weak, short-period windswell from the E-ENE. The ocean becomes a lake of small, mushy waves — mostly unrideable unless you are on a foam board. The wind does blow offshore often (over 50% of the time), but the energy is simply not there. Only the rare passing tropical system might throw a bone, but overall it is the true off-season.

December: Peak Winter Swell, Tricky Winds

December tops the charts with the highest average swell height at 1.6m and a period of 10.0 seconds. Swell is heavily concentrated from NE (42.9%) and NNE (24.3%), with ENE at 19.9%. These are full-fledged winter groundswells pushing serious energy. Unfortunately, ideal wind drops to just 38% — the lowest of the year — as strong northeasterly winds (ENE 46.9% at times over 30kph) create bumpy, choppy conditions. You need to pick the days when the wind backs off or goes lighter easterly to get clean, epic waves. But when that happens, the payoff is massive: powerful, long-period walls that will test your skills.
