December: Summer Mode Returns With Smaller Cyclic Swell
December closes the year much like it started: warmer water, stronger onshore breezes and a smaller average swell. The numbers settle at 6-7ft (2.0m) and 10.7s, the shortest average period of the year. SSW remains the standout in the wave rose at 29.1%, with SW at 18.1% and S at 14.6%, so there is still plenty of S/SW-origin energy moving through - just not as organized or as powerful as winter. The high-pressure-driven E/SE flow is back in force: E (16.6%), ENE (9.2%) and ESE (10.7%) combine for over 36% of all wind observations. WSW (15.6%), SW (12.6%) and W (6.8%) still offer clean offshore alternatives, and ideal wind sits at 25%. With water at 19.6°C and summer air averaging 20.8°C, it is a beautiful place to be - just expect more fun-sized days than heavy, hollow winter sessions.
