Conditions at The Alley in March
March: The Autumn Shift Begins
March marks the first genuine transition toward quality. Swell heights stay solid at 1.2m (4ft) and the average period pushes to 8.5s, while ideal wind percentages climb to 35 percent. E (44.5%) and ESE (30.0%) swells dominate, but the distribution broadens enough that 1-1.5m (3-5ft) surf remains common. On the wind side, SE (17.6%), SSE (19.2%), and S (12.2%) directions become more active, and the first meaningful SW/W offshore pulses start appearing after the summer troughs. Air temps cool to 24.5°C, water temps remain warm at 25.6°C, and precipitation drops to 4.83 mm/day. March is not yet consistent, but the trend is in the right direction, with cleaner windows and more legitimate long-period energy.
