Conditions at Mundaka in April
April: Cleaning Up and Backing Off
April represents the transition to spring. Average swell drops to 4.5ft (1.4m) and the average period falls to 10.7s; the waves become more rideable than heavy, though the swell direction is still nearly ideal. NW is responsible for 40.3% of the readings, WNW 22.8%, and NNW 18.1%, so the energy that does arrive is aimed right at the estuary. Most waves are in the 2-6.5ft (0.5-2m) range, with only a few bigger NW pulses. The point will still hold a 6.5ft (2m) swell and turn it into a world-class racetrack.
The trade-off is a drop in offshore wind consistency. SSW and S winds are less dominant at 4.7% and 4.9%, while WNW up at 12.4% and W at 9.2% leave the surface more exposed to onshore texture. That being said, high pressure in the Bay of Biscay often delivers gentle E/SE morning breezes in spring, adding those scarce windless days. With ideal winds at just 21%, April favors the surfer willing to sit through the bad days for a clean, punchy left. Air temperatures rise to 12.5°C, water temperature is 13.9°C, and precipitation is moderate-time to break out the lighter wetsuit.
