Conditions at Espinho in April
April: Spring Transition and Livelier Winds
April is the true transition month at Espinho. Average swell height eases to 4.3ft (1.3m), and the average period drops to 10.9s, a step away from the long-period power of winter but still enough to produce punchy, rideable waves. The wave rose remains west-heavy, with WNW at 43.7%, NW at 26.2%, and W at 18.5%, so the swell window is still generous. However, the size distribution is clearly shifting, with the largest chunk now in the 3-5ft (1-1.5m) range, and 6.5-8ft (2-2.5m) waves becoming less frequent.
Wind becomes the critical factor. Ideal conditions drop to 29%, and the strengthening pressure gradient over the Iberian Peninsula leads to a strong NNW flow at 23.4%, with NW at 8.5%. This northerly wind machine can put a textured, cross/onshore chop on the surface and make the waves less organized, although morning offshore ENE and E periods can still deliver clean shoulders. Air temperatures warm to 13.6°C, water temperature rises to 14.7°C, and rainfall is 3.09 mm/day. April rewards surfers who are willing to wait for a proper Atlantic low and then hit the first clean morning after the front.
