Conditions at Altura in March
March: The Last Reliable Winter Pulses
March is the final full month of reliable winter surf before the spring transition. Swell height holds at 2-3ft (0.8m), but period slips slightly to 7.4s. This month actually shows the strongest SE signal of the winter: SE swell is 14.0 percent of the total, with 5.7 percent in the 3-5ft (1-1.5m) category and another 1.6 percent at 5-6ft (1.5-2m). SSE, S and SSW add more southern energy, so the beach is still in the game. The catch is wind quality: NNW remains the top direction at 25.0 percent and NW is 9.1 percent, but ideal wind drops to 36 percent as spring onshore flow begins to mix in. Air temperature moves up to 14.8C, water is 15.8C, and rain averages 1.94 mm/day. Chase the days when a cold front clears and NW offshore flow meets the southeast swell.
