April: Swell Builds as the Southwesterlies Creep In
April is a transition month. The southern Indian Ocean remains extremely active, and the average swell height rises to 4.5ft (1.3m) with the period reaching 10.9s-all signs of solid groundswell. The direction focus is now firmly on SSE and S, with SSW adding a meaningful 15 percent. The swell-height distribution starts to spread: roughly 76 percent is still in the fun 3-5ft (1-1.5m) range, but nearly 16 percent now falls in the 5-6.5ft (1.5-2m) range and a small amount reaches 6.5-8ft (2-2.5m).
The problem in April is wind. The monsoon is mid-flip, and the ideal-wind percentage drops to 46 percent. West and west-southwest flow becomes increasingly common, putting a cross/onshore wind on Antiques and shortening the clean windows. Air temperature is 28.3°C, water is a balmy 30.1°C, and rainfall increases to 4.35mm/day. When pre-dawn NNW/NW offshore flow still manages to hold, the larger S/SSE swell can produce excellent, powerful reef waves; otherwise expect bumpy, wind-affected surf.
