Conditions at Devil's Rock in March
March: Late Winter, Still Punchy
March maintains serious winter size with a 7-8ft (2.2m) average swell and a 12.4s period, so the ocean still has plenty of push. The waverose shows NNW (35.0%) pulling ahead, with NW (27.3%) and WNW (9.4%) still adding meaningful west energy. The biggest change is the wind: ideal conditions drop to 45%, and NNW winds become more dominant (26.2% of all wind readings). That means more afternoons with cross-shore/onshore texture and shorter windows of clean, offshore conditions. Air temperatures warm to 17.3°C, water is 17.0°C, and rain remains at 1.15 mm/day. Catch the early mornings with an E/ENE breeze and you'll still find proper winter surf.
