Conditions at Playa de San Juan in April
April: The Transition Gets Tricky
April starts to lose the long-period punch of winter. The average swell height is still a respectable 1.5m (5ft), but the average period falls to 10.6s. Swell energy remains abundant from NNW (36.9%), NNE (23.8%) and N (18.9%), with a lot of 1-1.5m (3-5ft) surf plus some bigger sets. It is more average than powerful, and shape will depend heavily on the wind.
Wind is where the month struggles. Ideal offshore days drop to just 6%, while NNE wind dominates at 38%, aided by NNW at 18.9% and N at 13.2%. The overriding pattern is cool onshore flow. Air temperature rises to 18.4°C and the sea is 18.4°C, but the quality suffers unless a low-pressure system drags a southerly flow through the Alboran Sea.
