Conditions at Sao Lourenco in April
April: Swell Holds but the North Wind Bites
April marks the true shoulder season. Average swell height eases to 2.0m (6.6ft) and the period shortens to 11.1s. The swell window is still active, with NW at 28.0 percent, WNW at 21.3 percent and NNW at 20.0 percent, so there is no shortage of waves. However, the character becomes less consistent and more affected by local winds.
NNW winds dominate a hefty 28.6 percent of the time, while true offshore east-southeast winds are ideal only 13 percent of the time. That means a lot of cross-shore chop and below-par conditions. Early mornings and days with a deep low passing nearby can still produce fun, rippable 1.5-2.5m (5-8.2ft) surf. Water temperature is 15.7°C and air averages 14.7°C.
