March: The Autumn Transition Begins
The transition starts to show. Average wave height edges up to 1.6m (5-6ft) and period lengthens to 9.1s - a sign that more organized frontal groundswells are mixing in with the E/SE trades. S/SSW swell energy now approaches 11%, and the S component supplies a steady stream of 1.5-2.5m (5-8ft) waves. ENE/E/ESE still dominate the total spectrum around 49%, so you have to pick your day. Offshore NNE/NE winds remain frequent (39%) and ideal conditions hold at 33%. Air temp is 24.4°C, water 24.1°C, rainfall drops to 3.99mm/day. This is the last month to surf comfortably when the calendar and tide align.
