Conditions at Praia da Vieira in April
April: Fading Power, Rising Options
April marks the true transition into the less consistent spring season. The average swell height drops to 6ft (1.8m) and the period to 11.2s, with NW and WNW swells still dominant at 30.7% and 26.6%. The distribution shifts noticeably toward smaller classes: more 3-5ft (1-1.5m) energy and less of the heavy 6ft-plus (1.8m-plus) groundswell. Meanwhile, the NNW wind regime grows to 28.2% of all wind, and ideal offshore conditions drop to just 21% of the time. This means the best surf windows are often early arrivals before the afternoon wind kicks up, or during brief easterly/morning offshore patterns. Water temp climbs to 15.3°C and air temps average 13.8°C, so the first thinner wetsuit changes are possible, but the surf is no longer firing as consistently as midwinter.
