March: First Signs of Autumn and Longer-Period Swell
March is the bridge between summer and autumn. The average swell nudges up to 1.8m (5.9ft) and the period lengthens to 10.8s, which adds extra gearing to the S/SSW groundswell. S swell is 21.4%, SSW is 20.9%, and SSE/SE/ESE combine for 41%, so the direction spread is still broad. More importantly, the percentage of 1.5-2m (5-6.5ft) energy is growing, and the SSW and S rows carry a higher portion of 2-2.5m (6.5-8ft) waves. Wind patterns are shifting: ENE remains prominent at 20.5%, but WSW has risen to 14.5%, SW to 10.5%, and the offshore N/NNW/NW/WNW quadrants are becoming more frequent, with ideal conditions now 27% of the time. There will still be summer-style afternoons, but as cold fronts start pushing farther north, March offers a rising chance of clean, lined-up surf before the onshore seabreeze kicks in. Water temperature is 19.2°C, air temperature averages 22.1°C, and precipitation is 2.20 mm/day.
