Conditions at Cortegaoa in April
April: Spring Swell and the North Wind
April marks a clear step down. Average swell height falls to 4ft (1.3m) and period to 10.9s, while ideal wind conditions occur only 29% of the time. The swell mix is still dominated by WNW (43.7%) and NW (26.2%), but the energy is shorter-period and less powerful. The wind turns more northerly, with NNW (23.4%) and NW (8.5%) combining to create more onshore texture. When a low pressure drifts by, however, you can still get fun, rippable waves in the 1-1.5m (3-5ft) range. Water temps warm to 14.7°C (58°F), air temps average 13.6°C (56°F), and rain is moderate at 3.09 mm/day. April is about picking the windows - early mornings often bring a lull in the breeze before the north wind kicks up.
