Red Tree Reef - surf spot statistics

Best Surf Season (October - March)

The North Pacific roars to life during the autumn and winter months, delivering a sustained barrage of powerful, long-period groundswells to Red Tree Reef. Average swell heights climb above 2.5m, peaking at 3.0m in December, with periods consistently in the 11-12s range – that's the sweet spot for this west-facing reef. The dominant swell directions shift predominantly through the SW, WSW, and W quadrants, which align perfectly with the reef's optimal exposure. Offshore wind conditions are most reliable during this period, with ideal wind percentages hovering between 24% and 29%, often courtesy of high-pressure systems settling over the interior that pump clean ENE to SE breezes. When these ingredients combine, the reef fires, offering peaky, powerful waves that demand respect.

Fair Surf Season (April - May & September)

As the North Pacific storm track starts to weaken in spring, average swell heights drop to 2.2m in April and 1.7m in May, while periods shorten to around 10-11s. The swell energy is still present, but it becomes less consistent and more reliant on Southern Hemisphere pulses or late-season low-pressure systems. April sees the highest offshore wind frequency of the year at 30%, making it a prime month for clean, albeit smaller, conditions. September marks the transition back into winter, with average heights climbing back to 2.0m and periods picking up to 9.9s. While the swell is still building, the wind plays a trickier game – ideal conditions occur only 24% of the time, often requiring a careful eye on local pressure gradients.

Low Surf Season (June - August)

Summer slumps hard at Red Tree Reef. The North Pacific storm machine shuts down, leaving the reef relying on weak, distant Southern Hemisphere swells that arrive with less punch. Average swell heights bottom out at 1.3-1.4m, and periods dip to 9.8-10.2s – rideable but rarely exciting. The swell direction becomes heavily biased toward the SW and SSW, which, while still workable, doesn't bring the same juice as a solid W or WNW swell. To make matters worse, the wind is far from cooperative. Ideal offshore conditions fall to 21-23% of the time, with strong, persistent NW winds dominating a quarter of the days. The result is a summer of small, often choppy surf that is best suited for a longboard or a groveler when the occasional west wind swell aligns.

July: The Deepest Summer Slump

July is the bottom of the barrel in terms of surf quality. Average swell height hits an annual low of 1.3m, with a period of 10.2s. The swell is almost entirely from the SW (32.8%) and WSW (28.8%) quadrants, with SSW (17.2%) also in play. These directions are workable, but the lack of size and power means the reef rarely breaks with any real punch. The wind is uncooperative, with ideal offshore conditions only 21% of the time. NW winds are dominant at 20.7%, often fresh enough to put a nasty chop on the surface. The few quality windows come when a tropical storm or hurricane sends long-period energy from the south, combined with a rare light offshore flow – but those days are few and far between. For most, it's a time to travel or find a different wave.
