Conditions at Almagreira in April
April: Groundswell in the Balance
April marks a transition. The average swell height eases to around 7ft (2.1m), and the period drops to 11.2s, meaning Almagreira is still seeing genuine groundswell rather than summer windswell. The swell direction stats are striking: NW 25.1%, NNW 19.8% and WNW 19.7% - more than 64% of all swell comes from the ideal N/NW window. Size is predominantly in the 3-8ft (1-2.5m) band, so there are still plenty of punchy, hollow waves for experienced surfers.
However, the wind is shifting against quality. The NNW wind percentage jumps to 27.3%, with total N/NW/NNW winds running very high, while ideal offshore winds drop to 16%. This is the month when clean days become a rarer commodity. Water temperature rises to 15.3°C, air temps average 14.5°C, and rain sits at 2.08 mm/day - still enough to keep the ground cool but the ocean slowly warming.
