Conditions at Zipolite in April
April: The Swell Machine Revs
April is where the season takes off in size and period, with average heights reaching 1.5m (5ft) and period hitting 14.0s, the most powerful value so far. The swell is almost comically one-directional: SSW contributes 64.5% of all energy, SW 17%, S 11%, meaning over 90% of the waves are arriving from the favorable south quadrant. However, ideal wind drops to 41% for the month, the lowest of the year, as WSW/W/SW flows become more common in the afternoon. Still, morning offshore windows with NNW/NNE winds can produce pumping, long-period surf on the sandbars. Air temps average 29°C, water 29°C, and the first signs of the rainy season are just appearing.
