Conditions at Oscar Point in December
December: Summer Settling In, Texture Included
December closes the year with warmer air, lighter winds and a return to more manageable surf. Average swell height is 5ft (1.5m) with a 12.8s period, and the wave rose is packed with ideal-direction energy: SSW 87.7% and SW 10.0%. The height distribution is very surfable, with almost half of all waves in the 1-1.5m (3-5ft) range and another 34.3% at 1.5-2m (5-6.5ft). Wind, however, remains stubbornly from the S/SSW/SW quadrant-about 94% of observations-and true offshore flow is absent. But with air temps at 19.3°C, water at 17.4°C, and most winds under 20kph, December is far more pleasant than mid-winter. The early morning should be your target, before the southerly sea breeze rises and puts texture on an otherwise fun, long-period SSW swell.
