April: Bigger South Swell Meets the First Onshore Push
April marks the transition toward the wet season, and the signal is clear: ideal wind drops to 32% while the average swell height climbs to 1.2m with the longest average period of 14.0s. The tropical South Pacific is now producing serious long-period groundswell, and the SSW direction makes up 98% of the spectrum. A huge 78% of the observations fall in the 3-5ft (1-1.5m) range, with 6% reaching 5-6.5ft (1.5-2m). The problem is the wind: S and SSW become the dominant onshore flow, while the offshore N sector weakens to just 8%. Rain increases to 2.99 mm/day, air temperatures are around 28°C (23-34°C), and water temperature peaks at 29.6°C. Expect punchy, long-period surf with increasingly tricky, bumpy surface conditions.
