Conditions at Cactus in December
December: Official Start of the Low Season
December rounds out the year with a burst of warm weather and a return to full summer patterns. Average swell height is around 5.6ft (1.7m), average period 11.9s, and the SSW direction dominates with 55.3 percent of the energy, but the wind distribution is heavily weighted toward SSE and SE winds - a combined 44.5 percent of the time. Ideal offshore NNO-NO-ONO-O flow is present just 11 percent of the time. The result is a crowded, bumpy summer break: waves on paper, but often soft or lumpy on the surface. Water temperature climbs to 19.7°C and air temps average 21.2°C, which makes it tempting, but surf quality is at its lowest ebb. Park the hope for epic sessions until April.
