Conditions at Kastro Point in March
March: Fading Winter Swell with Early Spring Light
March is the first transition month. The average swell drops to 0.6m (2ft) and the average period slides to 5.5s, so the wave quality tends to become choppier and less organized. The south quadrant still contributes 25% of the swell energy - S (9.0%) and SSW (8.9%) remain the most favorable directions - but the heights are increasingly concentrated in the 0.5-1m range. Offshore winds blow only 23% of the time, and the dominant winds come from the ENE/E/ESE sector, which adds bump. Air temperatures lift to 8.8°C, rainfall eases to 2.59 mm/day, and water temperature stays at 14.9°C. March is a month for the glassy morning - when a NW offshore wind cleans up the lingering south windswell, Kastro can deliver a fun 2-3ft (0.6-0.9m) session. Just manage expectations.
