Conditions at Somo in March
March: Winter Energy, Spring Timing
March still belongs to the high season, though the engine is slowly starting to weaken. Average swell height drops to 6ft (1.8m), average period remains a solid 12.1s, and the NW sector still dominates - NW 41.7%, WNW 17.5%, and NNW 14.8%. There is slightly more N/NNE energy in the mix, but the vast majority of usable swell still arrives from the north-northwest. Ideal winds slide to 43% as the seasonal wind pattern becomes more variable; easterly and ENE winds appear more often, and W/WNW winds can create cross-shore chop. Still, when low pressure exits the Bay of Biscay and a S/SSW flow sets in, the average 5-8ft (1.5-2.5m) waves are powerful and well organized. Water temp stays cold at 12.9°C, air temps creep up to 10.9°C, and precipitation decreases slightly to 2.67mm/day.
