Conditions at Supertubos in May
May: The Lull Before Summer
May marks the definitive transition into summer surf. Swell height drops to 5.9ft (1.8m) and periods shorten to 9.9s - just on the edge of average to powerful. The swell is increasingly a product of distant low-pressure systems and storm swells that have become less frequent. Directionally, NNW (29.9%), NW (28.4%), and WNW (17.4%) continue to bring mostly wind swell and fading ground swell. For Supertubos, this means more groveling sessions and fewer solid barrels. The wind is favourable only 27% of the time, and the NNW thermal (38.3% of all wind) becomes the dominant feature, blowing 20-30kph for a large share of the month. Those east-northeast offshores are now rare, and when the westerlies do arrive, they quickly ruin the already marginal quality. Air temperatures become pleasant at 16.3°C, and the water reaches 16.3°C - spring suits are fine, but your expectations for a pumping day should be tempered.
