December: Peak Size and High-Stakes Wind Roulette
December is statistically the biggest month of the year at Shoals Point, with an average swell height of 10ft (3.0m) and a long-period 11.7s pulse. WSW and SW swells lead the pack at 19.5% combined, while E through SSE swell sits around 3.3%. The North Atlantic is relentless, and sustained 10-14s groundswell keeps wave heights elevated for days at a time. The wind is the ultimate gatekeeper: offshore W-NW flow sits at only 14%, while onshore ESE/SE/SSE winds pile up at 44%. This creates a stormy, often lumpy ocean, but it also means those rare post-frontal days - wind out of the WNW or NW, clearing skies, and a big W/SW swell wrapping into the point - can produce some of the heaviest surf of the entire year. Average air temps are 3.0°C, precipitation is high at 9.14 mm/day, and water temperature is 6.6°C. Bundle up and watch the forecast like a hawk.
