Supertubes - surf spot statistics

Supertubes in Australia is a high-performance wave that thrives on consistent ground swells and favorable wind conditions. The spot is dominated by ground swells year-round, with percentages rarely dropping below 89%, ensuring reliable wave energy. However, the best conditions for surfers are determined by a combination of swell size, consistency, and favorable wind conditions. Winter months (June, July, August) deliver the biggest waves, with mean swell sizes peaking at 2.2-2.3 meters, but these months also suffer from poor wind conditions around 78-79% of the time, making clean surf sessions less frequent. Autumn (April, May) and early winter (June) offer a better compromise with decent swell sizes (1.5-2.2m) and slightly improved wind conditions (36% good winds in April, 31% in May). Spring (September, October) sees a slight dip in swell size but maintains strong ground swell consistency, with October being one of the better months due to more manageable wave heights (1.7m) and 28% good wind chances. Summer (December to March) is generally smaller (1.2-1.4m) and plagued by onshore winds, making it less ideal for high-performance surfing. The optimal months for Supertubes are likely April and May, when swell size is solid (1.5-1.8m), ground swell consistency remains high, and the wind conditions are comparatively better than in winter. October is also a strong contender for those preferring slightly smaller but cleaner waves. If raw power and size are the priority, June and July deliver the biggest swells, but surfers will have to gamble with frequent onshore winds.
