Conditions at Revolcadero in April
April: Peak Spring Power and Long-Period Groundswell
April brings a serious step up in energy. The average swell height reaches about 4ft (1.2m), the average period stretches to 14.1s, and SSW dominates the wave rose with a massive 88.5% share, with SW adding 10.5%. This is about as clean a directional setup as a south-facing beach can get. Roughly 77% of the waves are in the 3-5ft (1-1.5m) class, while almost 10% push into the 5-8ft (1.5-2.5m) range; the 14-second periods give those waves real strength and form.
The main limiting factor is wind: ideal conditions drop to 48%, as the seasonal afternoon seabreeze becomes more active, especially from WSW and W. Rain is basically absent at 0.06mm/day, air temperatures average 26.5°C, and water temperature sits at 27.9°C. Dawn patrol is the move - early offshore/calm windows let you tap into the best April groundswell before the breeze gets up.
