December: Winter Ceiling and Waiting Game
December settles into the winter pattern at Rio de Coyula. Average swell height is back down to 4ft (1.2m) and period eases to 12.1s, keeping the surf rideable but less powerful than the summer months. SSW still leads the directional spectrum with 33 percent and S follows at 21 percent, but ENE and E swell now combine for about 17 percent, and ESE/SE add another 13 percent, so a significant portion of the wave energy is coming from unfavourable east-of-south directions that wrap weakly into the beach.
Wind continues to be kind, with ideal conditions 60 percent of the time. NNW, NW and WNW flow are the dominant wind story, all light, creating clean lined-up mornings. The dry season is in full swing with only 0.13mm/day of rain, air temperature at 27.5°C and water temperature at 27.2°C. If you are willing to wait for a true S/SW swell, December can still deliver surprises, but the overall tendency is for smaller, winter-lite surf.
