Conditions at El Brusco in December
December: Prime Time for Long-Period North Atlantic Swell
December along with January is the statistical peak of the surf year. The average swell height is 6ft (1.8m), the average period stretches to 12.6s, and El Brusco's north-facing exposure is pinned directly into the production zone. NW, WNW and NNW swells combine for more than two-thirds of all wave energy, with the most common waves falling in the 5-8ft (1.5-2.5m) range and a handful of XL days breaking overhead-plus. The standout stat is wind: ideal offshore flow is present 53% of the time, the highest of any month, thanks to frequent S/SSW/SW winds wrapped around Atlantic lows. These are prime conditions for clean, powerful, long-period waves. Air temps average 10.4°C (min -0.2°C, max 19.6°C), precipitation is 3.65 mm/day, and water temperature is 13.8°C. Break out the thickest wetsuit, wait for the right S/SW wind window, and December will deliver some of the best surfs of the year.
