Conditions at Itapeva in March
March: The Autumn Transition Begins
The first real taste of autumn arrives in March as the South Atlantic begins to wake up. Average swell height climbs to 1.5m (5ft) and the average period improves to 8.8s, so the waves start to develop a bit more punch. The directional spread is healthier: ESE at 22.3 percent, E at 20.7 percent, SE at 18.5 percent and SSE at 15.3 percent, with ENE down to 10.0 percent. More SE and SSE energy means Itapeva's east-southeast exposure is being fed from more favourable angles. The wind is still predominantly from the NE quadrant - NE at 20.2 percent, NNE at 17.1 percent - but the offshore W/WNW/NW/NNW component begins to show up more often. The ideal wind percentage is 28 percent. Water temperature remains warm at 23.7°C, air temperature averages 21.7°C, and the surf is worth watching whenever a cold front crosses the state and delivers pre-frontal NW winds.
