Conditions at Zurriola in April
April: The Northwest Holds While the Wind Plays Games
April marks a true transitional month in the Basque Country. The average surf height eases to 1.5m (5ft) and periods drop a full second to 10.8s, so the swell loses some of its winter bite. But the direction remains astonishingly good: NW swell is at its yearly peak of 39.3 percent, WNW at 29.2 percent and NNW at 15.5 percent - a combined 84 percent from the exact directions Zurriola is designed to handle. For surfers who prefer fun-sized, rippable waves, this is actually a blessing. The challenge is the wind. Ideal conditions fall to 32 percent as the onshore quadrant grows: NNW 11.7, WNW 11.3 and NW 10.6, plus N at 3.5 percent. The southerly flow is still present (S 8.4, SSE 7.7, SSW 4.9, SW 3.7, WSW 4.7), but the spring sea breeze becomes more frequent. The water warms to 13.9°C and air averages 12.2°C, so the lineup starts to feel slightly more comfortable. Expect a mix of clean, shapey days and bumpy onshore afternoons - a month for flexible scheduling.
