April: The Long-Period Groundswell Engine
April solidifies the pattern: SSW swell explodes to 58.8% of all observations, and the average period jumps to 12.8s, one of the best of the entire year. Average height sits at 1.5m (5ft), but the quality of the lines is significantly better thanks to the long-period groundswell. The trade-off is wind: only 32% of the time is ideal, with southerly winds at 29.5% and NNW at 18.2%. This can create lumpy surface conditions, so look for the morning offshore windows. Water temperature climbs to 28.8°C, air averages 28.2°C, and rainfall remains limited at 0.32mm/day.
