Reef seasonal overview

Best Surf Season (October - March)

The North Atlantic winter machine is in full swing from October through March, delivering consistent, powerful swell to this west-facing reef. Average wave heights range from 2.0 to 2.6m with periods often exceeding 12 seconds, providing the long-period, pumping surf this spot is known for. While wind conditions are not always perfect, the percentage of ideal offshore flow from the WNW, W, WSW, and SW quadrants climbs above 20%, with December peaking at 25%. When a strong low-pressure system spins up in the North Atlantic and we get a clean breeze from these directions, the reef absolutely fires.

Fair Surf Season (April, May, September)

Transition months bring a mix of leftover winter energy and the first hints of summer. Swell heights average between 1.6 and 2.0m, with periods dropping to the 10-11 second range. The wind becomes less reliable, with ideal conditions occurring only 10-14% of the time. Still, occasional groundswell from late-season storms can light up the spot, especially in September when the Atlantic starts to stir again.

Low Surf Season (June - August)

Summer settles in with a marked drop in swell energy. Average heights hover around 1.4-1.5m, periods in the 8-9 second range, and ideal wind conditions drop to a meager 3-6% of the time. Dominant north/northwest winds keep the spot often choppy and onshore. However, if you catch a rare WNW or W breeze during a small northwest swell, the waves can clean up for some rippable summer fun.

Conditions at Reef in May

May: The Lull Begins

May sees a notable drop in swell energy with an average height of 1.7m and period of 9.9s, now in the average, punchy range. Swell is still mostly from NW (30.5%) and NNW (31.5%), but also some WNW (17.4%), meaning the reef gets plenty of knee-to-waist high swell. The real issue is wind: ideal conditions plummet to 10% of the time, with relentless north winds (N at 29.8%) and strong NNW flow (19.4%) keeping the surface choppy. The best chance for a good session is during brief periods when a low slides east and the wind clocks around to the west quadrants early in the morning. Grab a groveler and manage expectations.
