April: First Major Groundswell of the Winter
April is where the season goes from good to excellent. The average swell height remains a solid 6ft (1.8m), but the period lifts to 10.7 seconds and the combination of S, SSE and SSW swell begins to dominate the spectrum. The SSE component alone is 17 percent and direct S adds another 18 percent, producing a lot of chunky swell lines in the 5-8ft (1.5-2.5m) range. Offshore wind frequency climbs to 49 percent, with NNW, NW and WNW directions combined around 35 percent of the time. This is the classic recipe at Wainui: long-period groundswell wrapping into the east-southeast-facing beach while westerly offshore winds groom the faces. Water temperature drops to 18.5°C and average rainfall increases to 3.14mm per day as fronts become more active. Most of April offers consistent, powerful, perfectly rideable surf - a month that should be circled on any surfer's calendar.
