Conditions at Spiders in April
April: Size Remains, Period Fades
April is the hinge month. The average wave height is still a respectable 6.5ft (2.0m), but the average period drops to 10.9s, taking away some of the punch that made winter so good. The swell rose becomes even more dominated by NNW, with a massive 46.3 percent; NW adds another 23.9 percent, while true W/WNW is reduced to under 8 percent. This means less of the ideal westerly energy and more mid-length NNW groundswell and cross-swell combo. The wind outlook is less cooperative, with ideal offshore conditions only 35 percent of the time; strong NNW/NW winds make up more than half the wind rose, creating bumpy surfaces on many days. Air temps are pleasant at 19C and water holds at 17.1C, but the best waves will require some patience and a dawn patrol mindset.
