Conditions at Biarritz in April
April: Cleaner Skies, Fading Energy
April brings the first true spring setup. The average swell drops to 4ft (1.2m) and the period shortens to 11.0s. Direction remains excellent - WNW 42.1 percent, NW 40.4 percent and NNW 10.0 percent combine for over 92 percent in the sweet spot - but the height distribution shifts toward 2-5ft (0.5-1.5m). Solid 5-6.5ft (1.5-2m) waves now make up only around 13 percent of readings.
Winds become less reliable: onshore/cross-shore W (12.8 percent), WNW (12.4 percent), NNW (11.9 percent) and NW (11.3 percent) dominate the rose, though most are light. The wind is ideal for surfing only 29 percent of the time, favoring early mornings and days when a weak southerly flow sets up. Water temp rises to 14.1°C and air averages 11.9°C. It is more fun-sized than firing, but the beaches can still deliver.
