May: The Trade Winds Take Over
May marks the real arrival of the southeast trade wind season at Sero Beach. The average swell jumps to 1.3m (4.3ft) and 88.1 percent of the spectrum is SSE, with 38.3 percent in the fun 1-1.5m (3.3-4.9ft) range and 20.5 percent in the pumping 1.5-2m (4.9-6.6ft) class. The 2-2.5m (6.6-8.2ft) class also starts to show, at 4.2 percent. Periods stay around 7.6s, meaning this is mostly trade-wind-generated swell rather than long-period groundswell, but there is energy to burn.
Wind is the spoiler. Ideal surf wind drops to just 9 percent, with SE wind dominating at 48.7 percent and ESE wind adding 17.1 percent. That is a full-blown onshore setup for a southeast-facing beach, and it puts a bumpy, textured surface on even the best swell lines. Precip falls to 2.34mm/day and the water cools to 27.4°C, a small relief from the wet season. Surface chop and drift will test your paddle fitness; look for standout sandbars or any reef shelter to make the most of this punchy but windblown swell.
