Conditions at Beliche in December
December: Deep Winter Punch
December delivers one of the biggest and most powerful average surf months of the year at Beliche. Average swell height is 8ft (2.4m), the period is 12.6s, and the Atlantic is in full storm mode. NW (23.7%) and WNW (15.1%) swells lead the way, with NNW (10.9%) and W (5.2%) adding more westerly energy; SW and WSW directions are still a small but increasingly important part of the mix at 1.2% and 2.5%, respectively. The wind picture can be messy: NNW winds are far less dominant than in summer at 14.9%, while E/ESE winds become more common and S/SW components can show up as storms approach. Ideal N/NE offshore conditions occur about 26 percent of the time. Water temperature is 16.6°C, air temperature averages 14.9°C, and December is wet with 2.97mm/day of rain. When lows track along the southern edge of the North Atlantic storm corridor, Beliche lights up with heavy, long-period waves.
