Conditions at Yallingup in April
April: The Sweet Spot Arrives
April is where Yallingup's season comes together. The average swell height climbs to a robust 6.5ft (2.0m), the period extends to 12.8s, and the directional spread improves significantly. While SW still leads at 42 percent, WSW now adds 12 percent, W adds 3 percent, and W/NW components are present, meaning the WNW-facing reefs finally catch a larger share of the open-ocean energy. The 5-8ft (1.5-2.5m) range dominates, and with these longer periods, the better swells produce thick, powerful and often firing waves.
The wind story is equally positive. April posts the highest ideal-surf wind percentage of the year at 28 percent, with ESE/SE winds increasingly common and the SW seabreeze less aggressive as inshore water temperatures start to cool. Air temperature is still pleasant at 19.4 degrees C (min 13.5, max 27.8), water temperature is 21.1 degrees C, and rainfall increases to 1.23mm/day as the first autumn fronts brush the region. This is the month to block out the calendar.
