Conditions at Coxos in May
May: Groundswell Fading, Summer Pattern Forming
May is when summer starts to tighten its grip on Coxos. Average swell height slides to around 5.6ft (1.7m), and average period falls to 9.9 seconds, meaning more mid-period, punchy waves but less of the deep Atlantic groundswell of winter. The swell rose is dominated by NNW at 31.5 percent and NW at 30.5 percent, with WNW still contributing 17.4 percent. Those northern pulses are often windswell from the same systems driving the approaching summer trade winds, so expect lined-up but softer waves rather than heavy barrels. Ideal offshore wind is down to 11 percent. NNW winds blow 36.5 percent of the time, making surface conditions bumpy. Still, with air at 16.7°C, water at 16.5°C and rain at 1.48 mm/day, May is pleasant. Grab a smaller board and hunt for the early windows.
