April: Cleaner Winds, Still Getting Size
April marks the start of the transition season, yet it does not look like a typical spring slouch. Average swell remains a solid 6ft (1.9m) with an 11.1-second period, and the dominant NW direction pumps out 31.3 percent of the waves, with WNW and NNW lifting the north-west share to 69.7 percent. What really improves is the wind: ideal-wind frequency jumps to 48 percent, and a powerful NNW flow (30.7 percent) combined with NW (12.2 percent) helps groom the surface. This makes April an excellent month for quality, slightly smaller waves. Air temps reach 15.1°C, water 15.7°C, and precipitation is still moderate at 1.78 mm/day. The beach becomes more user-friendly while retaining enough period to hold the sandbar together on the best days.
