Conditions at Rio de Coyula in May
May: Southern Hemisphere Swell Peaks
May rolls out the best all-round groundswell window of the year. The average wave height rises to 5ft (1.6m), the period peaks at 14.2s, and SSW swell accounts for a massive 74 percent of the direction spectrum. Add S at 13 percent and SW at 8 percent and you are looking at a beach tuned directly into long-range South Pacific storm swell. The 1.5-2m (5-6.5ft) class is well represented, so head-high-plus waves are common and the outer banks start to show real intensity.
Wind quality returns to a healthy 51 percent ideal. The offshore N-NW flow is still reliable through the morning, while afternoon SW/W wind makes a late appearance. May is also when the rainy season begins, with precipitation jumping to 1.74mm/day, but the warm air at 29.7°C and very warm water temperature of 29.9°C keep things pleasant between showers. If you want powerful, long-period south swell in warm water, May is hard to beat.
