Conditions at Hondarribia in April
April: Smaller but Cleaner
April is the shoulder season. Average swell sizes ease to 1.5m (5ft) and the period drops to 10.8s-still in the rideable, punchy range, but the raw winter power has faded. The northwest quadrant absolutely dominates: NW at 39%, WNW at 29%, and NNW at 16%. That means Hondarribia continues to see consistent surf, just with a more spring-like texture and plenty of chest-to-head-high days.
Wind statistics show a shift toward lighter, more directionally mixed conditions: WNW and NNW are the most common at 12% each, with W at 12% and NW at 10%. The ideal surf-wind percentage holds at 31%, and the higher number of light morning winds means you can catch clean waves before the thermal northwesterly kicks in. A favorable SSW/SW flow still produces the best shape.
Spring warmth is building-air temps average 12.2°C, water temp 13.9°C, and precipitation is moderate at 2.98 mm/day. The water is still too cold for boardshorts, but the lighter winds and smaller size make April an excellent month for sharpening your rail game after winter.
