Conditions at Ericeira in April
April: Shoulder Season Shuffle
April marks a true transition. The average surfable swell drops to 2.0m (6.5ft) and periods fall to 11.1s - still rideable, but noticeably less powerful than winter. The swell direction remains mostly NW and NNW, with WNW still a major contributor; W and WSW pulses occasionally fill in from Atlantic lows tracking further north. The tricky part is wind: ideal offshore flow occurs only 15% of the time, while the persistent NNW wind regime begins to strengthen. That means many days are cross-shore or bumpy. Still, when a cold front sweeps through and high pressure builds inland, offshore E/NE flow can groom the points into clean, hollow 4-6ft (1.2-1.8m) waves. Air temps average 14.7°C, water climbs to 15.7°C, and spring showers remain possible. Pick your windows and April can still deliver.
