December: Cementing the Cleanest Month of the Year
December is statistically the cleanest month at The Wedge, with ideal wind 47% of the time - the highest of any month. The average swell height is 2-3ft (0.8m), and the average period is 12.3s. Swell direction is dominated by W (42.6%) and WSW (33.4%), with SW at 16.0%. The Wedge is not as perfectly aligned for this west-heavy direction as it is for pure SW, but the long period and the jetty's intense refraction mean the best W/WSW pulses still arrive as fast, heavy, wedging waves. Offshore winds are abundant: NNW (9.9%), NW (8.6%), NNE (8.5%), NE (6.4%), and N (3.7%) add up to over one-third of the wind measurements. Air temperature averages 14.8°C, water temperature is 14.8°C, and rainfall is 1.86mm/day. For clean, powerful, wintry Wedge waves, December is the month to circle on the calendar.
