March: Autumn Transition and Cleaner Edges
March is where the change begins. The average swell height rises to 1.5m (5ft), the period stretches to 8.8s, and the ideal wind frequency reaches 37%. Swell direction shifts a bit toward the south, with east-southeast at 22.3%, east at 20.7%, southeast at 18.5% and south-southeast at 15.3%. These are good directions for Prainha, and the longer-period pulses start to produce more powerful, lined-up surf. The northeast trade wind is still present at 15.0%, but post-frontal west-northwest and northwest winds become more common. Water temperature remains warm at 23.7°C, so autumn surfing is comfortable. March is a fair season month, but the good windows are getting easier to find.
