Gas Bay
Gas Bay is a quality right-hand reef break just south of Margaret River main break that delivers hollow, workable walls when the swell is right. It picks up more swell than many nearby breaks and is surprisingly consistent even in summer months—surf-forecast lists February as the best month for clean waves here. The reef creates a defined takeoff zone and the wave runs along a shallow ledge, offering barrel sections on bigger days.

Frequently Asked Questions
What kind of wave is Gas Bay?
Gas Bay is a reef break in Margaret River, Australia, that mostly breaks right.
What swell works best at Gas Bay?
Gas Bay picks up swell from the SSW round to the W, and it's best when it's coming straight out of the SW. It starts working at around 0.8m and handles up to about 3m, with the sweet spot around 1.8 to 2.5m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak.

An E wind is dead offshore at Gas Bay, and anything from the NE round to the SE keeps it clean. The morning is typically the best window, roughly 5am to 10am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
