Conditions at Avalanche in January
January: The Sweet Spot of Summer
January is arguably the most consistent month for clean conditions at Avalanche. The summer high pressure ridge keeps average air temperatures around 21.9°C and water temperatures at 20.4°C, and the ideal offshore wind window-S, SSW, SW and WSW combined-reaches 28 percent, the joint best of the year. The swell rose is dominated by southerly quadrant energy, with SSW at 29.6%, S at 16.9% and SW at 13.7%; wave heights average 6-7ft (1.9m) with a healthy 10.8s period. The problem is that almost none of that energy arrives from the optimal N-NNE-NE-ENE window, so the beach relies heavily on wrap-around SSW/SW swell. When the E/ENE cross-shore breeze, which makes up 18.5% and 9.3% respectively, gives way to a WSW/SW offshore flow, Avalanche can offer clean, long-period surf.
