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.

June at Supertubes delivers consistent swell with an average height of 2.2m and a solid 13.5s period, providing powerful, well-formed waves ideal for experienced surfers. The dominant swell direction is from the WSW, contributing the majority of waves in the 1-2.5m range, with a higher frequency of 1.5-2m waves (13.58%) and 2-2.5m waves (10.23%). This creates long, hollow rides when conditions align. While the wind is only favorable 21% of the time, the data shows lighter winds (0-20kph) are more common from the E to SE, offering occasional clean, groomed conditions. Stronger winds (20-40kph) prevail from the W to NW, which can lead to choppier surfaces. The spot thrives on larger swells, with a notable percentage of waves over 2.5m (0.87% WSW, 0.61% W), ensuring high-performance days for those chasing bigger barrels. Expect a mix of onshore and cross-shore winds, requiring patience for optimal sessions.
