Red Tree Reef seasonal overview

Red Tree Reef is a reliable year-round surf spot, but the best conditions for surfers are concentrated in the winter and early spring months. From November through February, the swell consistency is excellent, with ground swell dominance (67%–82%) and minimal no-swell days. December and January stand out as prime months, offering the largest mean swell sizes (2.8m and 2.4m, respectively). However, these months also come with challenging wind conditions—bad winds prevail over 80% of the time, making clean sessions less frequent. February and March still provide solid swell (2.2m–2.0m) with slightly improved wind percentages (23% good wind days). April marks a transition, with ground swell decreasing (59%) and wind conditions marginally better (29% good winds). The summer months (May–September) see smaller swells (1.1m–1.6m) and a higher mix of wind swell, making conditions less ideal for advanced surfers. October brings a return of larger swells (2.1m) but retains poor wind reliability (79% bad winds). For the best balance of size and fewer onshore days, late winter and early spring (February–April) offer the most favorable trade-offs, though patience is needed for clean windows.

Conditions at Red Tree Reef in September

Red Tree Reef in September offers consistent surf with an average swell height of 1.6m and a solid 10.8s period, providing quality, well-spaced waves. The swell is predominantly from the SSW to WSW directions, with the highest frequency of waves in the 1-2.5m range—ideal for intermediate to advanced surfers. Wind conditions are favorable only 23% of the time, with light to moderate speeds (10-20kph) from the SW to W directions being most common. However, stronger winds (20-30kph) from the S-SSE can occasionally create choppy conditions. The best sessions will likely occur when winds are light and offshore or cross-offshore, aligning with the dominant swell direction. Overall, September delivers reliable surf but requires patience for optimal wind windows.
