Conditions at El Sardinero in April
April: Shoaling Shoulder Season
April signals a clear shift toward lighter conditions. Average swell height drops to 5ft (1.5m) and period to 10.8s, so waves become more average, punchy and rippable rather than heavy. The swell direction still favors the northwest, with NW at 43.4%, NNW at 20.7% and WNW at 17.2%, but the energy is increasingly in the 2-5ft (0.5-1.5m) range. Ideal wind frequency falls to 39%, and the wind rose begins to show more ENE/ESE flow, which is onshore at the ENE-facing beach. The good news is that April can still deliver lined-up west-northwest swell during the first half of the month, and water temp starts creeping up to 13.7°C. It is a transitional month: fun when a low pressure lingers in the Bay of Biscay, smaller when the Azores High starts to build.
