December: The Summer Trade-Wind Swap
December signals the return of summer. The offshore wind frequency is still reasonable at 20%, but the overall pattern becomes dominated by NE (10.3%), ENE (18.4%), E (25.6%), ESE (17.6%) and SE (15.3%) sea breeze and onshore flow. Average swell height sits around 3-5ft (0.9-1.5m) and the period is 7.5s, so most waves are short-period, windswell-style E-ENE energy. Tropical cyclone season is beginning, which can occasionally spin up larger NE-to-E swells in the 5-8ft (1.5-2.4m) range, though often accompanied by strong onshore winds. With water temperature at 25.0°C and air temperatures averaging 24.0°C, keep an eye on dawn sessions and weekend wind changes.
