Conditions at Anne Avenue in December
December: Midsummer Drift
December completes the return to summer in earnest. Swell height falls to 8ft (2.5m), period shortens to 10.9s, and ideal wind remains at 23%. The wind rose is dominated by the E/ESE/SE onshore pattern at 42.6%, and much of the wave energy is generated locally as short-period windswell. While the E/ESE/SE swell window is actually one of the biggest of the year at 11.3%, it is rarely clean because the wind and waves come from the same destructive direction. The S/SSW/SW groundswell still provides background pulses, but without offshore wind the spot gets lumpy and sectiony. Water temperature reaches 19.3°C and air averages 20.3°C, making it the start of the warm-water season - but cold, clean winter surf is six months away.
