Conditions at Red Tree Reef in December
December: The Peak of the Peak
December is the heaviest month at Red Tree Reef. The average swell height reaches 10ft (3.0m) with an average period of 11.7s, putting this squarely in massive-to-charging territory. WSW (10.3%), SW (8.5%), and SSW (5.8%) provide the bulk of the energy, but the W and WNW contributions, though smaller, are the ones that make this reef truly magical. With more 8ft+ (2.5m+) waves than any other month, December delivers size, power, and consequence-this is serious big-wave lineup territory.
Wind still limits how often it all comes together: ideal conditions just 25% of the time. The month is stormy, with strong ESE/SE winds, cold temperatures, and heavy precipitation (9.14 mm/day). But the post-frontal windows-when the sky clears and the offshore ENE/E/ESE breeze grooms the faces-are some of the best waves you will ever see at Red Tree Reef. Water temp is 6.8°C (44°F), air temps hover near freezing, and the winter wetsuit is absolutely essential. Bring experience, respect the size, and wait for the wind to cooperate.
