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 December

December at Red Tree Reef delivers solid surf conditions, with an average swell height of 2.8m and a powerful 12.4s period, indicative of well-spaced, clean energy. The swell distribution favors WSW (8.08% of waves in the 2-2.5m range) and SW (6.07% in the 1.5-2m range), ensuring consistent, rideable waves. While smaller swells (1-1.5m) from WSW and SW also contribute, the bulk of the action comes from mid-to-large swells, offering punchy, high-quality walls. Wind conditions, however, are less ideal—only 6% of the time do winds align favorably for surfing. Predominant winds are from the SW to WSW, often blowing at 20-40kph (notably 3.22% at 30-40kph WSW), which can create chop or cross-shore interference. S and SSE winds occasionally bring cleaner offshore setups, but they’re rare. Advanced surfers will find the best sessions when SW/WSW swells coincide with lighter or offshore winds, but patience is key—expect thicker lips and heavier drops due to the reef’s response to larger winter energy. Pack a step-up board for the overhead+ days.
