Conditions at Arrifana in April
April: Spring Mix, Good but Less Predictable
April marks a clear transition. The average swell drops to 1.9m (6ft) and the period eases to 11.1s - still enough power to make steep, fun-sized waves at Arrifana. NW swell now accounts for 34.1% of all energy and WNW adds 21.5%, while the direct W window remains at 6.4%. The biggest issue is wind: ideal conditions only occur 34% of the time, with strong NNW winds blowing 28.0% of the month and NW adding another 14.5%. Those north winds create lumpy surfaces and mostly affect the afternoon. Look for dawn patrols, early offshore flows and the sporadic low-pressure pulse to get the best of April. Water temps nudge up to 16.0C and the air is milder at 15.1C.
