Gas Chambers is a reef break in North Shore, Oahu, USA, that mostly breaks left over a reef bottom. On its biggest days it can hold faces of around 4m. A shortboard is the usual call.
Gas Chambers picks up swell from the WNW round to the NW, and it's best when it's coming straight out of the NW. That's a tight window, so it needs the swell direction to line up. It starts working at around 1.2m and handles up to about 3m, with the sweet spot around 2 to 2.6m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An ESE wind is dead offshore at Gas Chambers, and anything from the E round to the SSE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Gas Chambers is at its best around the low to mid tide.
The most reliable run of swell at Gas Chambers comes Nov to Feb. There's a second window in Mar and Oct too. Nov-Feb. Between Rocky Point and Pipeline.
The water at Gas Chambers averages around 25°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.
