Conditions at Amoreira in April
April: Shifting Gears and Cleaner Spring Windows
April marks a clear transition. Average surf height eases to 6ft (1.9m) and the average period drops to 11.2 seconds, yet there is still plenty of rideable energy. NW swell is the clear leader at 35.7 percent, with WNW at 24.5 percent and NNW at 10.1 percent. The storm track starts to shift north, but spring lows can still deliver good groundswell. The bigger issue is wind. The ideal wind percentage falls to 19 percent, while NNW winds dominate a full 28 percent of the time, with NW adding 14.5 percent. Onshore and cross-shore conditions are frequent, so early-morning slots and lighter wind days are the keys. Water temperature climbs to 16.0°C, air averages 15.1°C, and spring showers are still common. Board choice shifts from big-wave weapons to standard shortboards and hybrids.
