Conditions at Osbourne in March
March: The Spring Transition Begins
March still carries serious winter punch, with an average swell height of 5-6ft (1.6m) and an 8.7s period. The direction distribution begins to shift slightly more favorably, as SSE (8.3 percent), SE (8.1 percent), ESE (6.5 percent), and E (6.3 percent) combine to push the optimal window to nearly 30 percent of the total swell. SSW (16.0 percent) and S (11.6 percent) remain the largest individual contributors, meaning wrapped or refracted southerly swell can still break along the beach. Winds are favorable with NNW (12.3 percent), WNW (9.5 percent), W (9.1 percent), and NW (9.0 percent) dominating, and the wind is ideal 26 percent of the time. Water temperature is still freezing at 0.9°C, while air temperature creeps marginally higher to -0.1°C. Precipitation remains frequent at 3.08 mm/day, but the lengthening daylight and more frequent NW flow ahead of cold fronts make March a month where winter-sized waves can still line up with clean conditions.
