Conditions at Raglan in December
December: Summer Setups and Westerly Swell
December finds Raglan in early summer mode. Average swell height drops to 1.7m (5.6ft) with the shortest average period of the year at 11.3s. WSW still dominates at 43.6% - the highest of the year - with SW at 18.6% and W at 12.3%, so there is no shortage of wave direction. But ideal wind frequency is just 19% as afternoon NW sea breezes and occasional W/NW onshores plague the Point. The mornings, however, can be glassy and fun, especially with water at 18.7°C and air at 17.0°C. Swells are more inconsistent and less powerful than autumn, but the warm-water, shoulder-high days make December a cruisy month for a surf trip - just surf early and avoid the afternoon bump.
