Conditions at Louro in March
March: Waning Winter Energy, Still Solid
March is the last truly consistent winter month. Average swell height eases to around 5ft (1.5m) and though the period drops a bit to 11.8s, there is still plenty of ground-swell punch. WNW remains the biggest player at 30%, while the preferred S-SSW-SW-WSW window totals about 12.3%. Offshore winds still blow 41% of the time, led by NE (16.5%) and NNE (12.9%), which keeps the sandbar groomed on the best days. The onshore S/SSW/SW/WSW influence begins to slacken, but still accounts for roughly one third of the wind spectrum, so weather windows are key. Water temp holds at 13.3°C, air temps average 12.0°C, and the sun starts to stretch the sessions.
