April: Clean Power in the Transition
April still delivers substantial surf even as winter loosens its grip. Average swell height is around 7ft (2.2m) with a solid 11.4s period, and the W and WNW combination accounts for nearly half of all swell observations. The height distribution is broad, from rippable 3-5ft (1-1.5m) waves to pumping 5-8ft (1.5-2.5m) sets. It is a great month for quality groundswell, if you can find the right wind.
The catch is wind: ideal offshore wind time falls to 20%. The spring northerly machine begins to spin up, with NNW at 18%, NW at 9% and N at 4% combining for significant cross-shore energy. S and SSW winds are still around too, especially before frontal passages. Air temps average 8.2°C, water temperature is 10.7°C, and rainfall drops to 4.58mm/day. Early mornings are the golden window, often glassy before the north wind grabs the coast.
