About Gas Bay
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces W (261°), so it takes swell from the W. The wind blows offshore from the E (81°). It is exposed to the open swell. It suits expert surfers. It works in 3–20 ft of swell. The sea floor shelves moderately: 10 m deep about 250 m out (1 in 27). On a typical 5 ft, 11 s swell the waves here would crumble. The sea is about 18°C in September, its coldest month (2 mm shorty), and 22°C in March, its warmest (2 mm shorty). The town to stay in is Margaret River, 9.3 km away (about 20 min by car). Within 5 km we also list 9 surf spots and 1 wind sports spot.
Water about 19°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
