Conditions at Periscopes in April
April: The Trade-Wind Switch
April marks a major step up in quality. The southeast trades have largely taken over, with ESE (23.0%), SE (15.0%) and E (13.2%) dominating the wind rose, and ideal surfing conditions now occur 78% of the time. That offshore/easterly flow is exactly what a west-facing setup like Periscopes needs to keep the surface clean. Swell is still running strong out of the SSW (72.3%) and SW (21.8%), averaging 1.3m (4ft) but with a very solid 13.9s period. The longer interludes of glassy dawn wind make the most of that energy, and the 1.5-2m (5-6ft) band appears 22% of the time. Rainfall drops to 3.44mm/day, air temperature is around 27.7°C and water temp is 29.3°C. This is the beginning of the premium season.
