Gas Bay

Best Surf Season (April - September)

April through September is prime time at Gas Bay. The west-southwest facing beach sits directly in the firing line of the Southern Ocean storm track, and once autumn arrives the swell machine switches on. Monthly average wave heights climb from 2.0m (6.5ft) in April to a peak of 2.8m (9.2ft) in July, while swell periods hold in the powerful 12.8-13.3s range. The dominant SSW and SW groundswells are exactly the directions Gas Bay needs. It is not all glory, though; winter also brings a lot of westerly and southwesterly wind, which is onshore here. Ideal northeast offshore flow only arrives about 18-29% of the time. The best days are the classic post-frontal windows when a strong high pressure ridge builds over the Bight, winds go light offshore, and long-period south-west swell lights up the bank.
