Conditions at Esposende in April
April: The Fateful Shoulder
April is where Esposende starts to shift from powerful winter machine to iffy spring break. The average swell height is still a respectable 2.1m (7ft), but the average period drops to 10.9s, signalling less pure groundswell and more locally generated pulse. The swell rose is loaded with NW (22.3%), WNW (21.9%), NNW (15.7%) and W (9.1%), so direction is not the problem; energy and period are slowly fading.
Wind becomes the critical factor. Ideal wind windows fall to 33%, as NNW flow becomes the dominant player at 21.0% and NW adds another 9.8%. The result is more afternoons with bumpy, cross/onshore conditions. Still, early mornings and pre-frontal days with offshore ENE-E-SE wind can deliver clean, hollow bank surf. Water temp rises to 14.6°C and air averages 13.2°C, so many surfers switch to a 3/2 or a 4/3 if they are sensitive to cold. April is a month for flexible surfers who watch the wind more than the swell chart.
