Conditions at Penascal in April
April: More Power, Fewer Windows
April marks the real autumn turn. The average swell height jumps to 1.7m (5.6ft) with a 13.6s period, the longest average of the year, and the swell direction is almost absurdly consistent: SSW supplies 91.8% of all wave energy. This is a powerful groundswell month, with 58.9% of heights in the 1.5-2m (5-6.5ft) range and 17.9% in the 2-2.5m (6.5-8ft) range. The bad news is the wind. Ideal offshore wind disappears to 0%, while S (46%) and SSW (40%) combine for 86% of observations, many of them in the 10-20kph range. These onshore/cross-shore breezes will rake the faces and close out hollow sections. Water temperature cools to 17.5°C, air drops to 19.9°C, and the surf is best in the sheltered corners.
