January: Summer Trade Swell and the Sea-Breeze Battle
January at Avalon is a tale of plenty of swell but a persistent battle with the wind. The average wave height sits at 1.3m (4.3ft) with an average period of 8.2s, which fits the average, punchy and rideable bracket. The wave rose shows a huge easterly presence: ENE 21%, E 22%, ESE 16%, SE 18% and SSE 17%. That means the favorable E/ESE/SE/SSE directions together account for around three-quarters of all swell energy. However, wind is the limiting factor. The wind rose is dominated by NE/ENE and SSE/S flow, and ideal offshore W-to-NNW winds are only on the board about 21 percent of the time. Under a summer Tasman High, the classic NE sea breeze kicks in by late morning and turns the surface lumpy. Water temp is a warm 22.3°C, air temp averages 23.2°C, and rainfall is around 3.01 mm/day. Dawn patrol offers the best chance of clean 3-5ft (1-1.5m) peelers, while strong SSE lows can push 5-6ft (1.5-1.8m) sets through in the early hours.
