Conditions at Sao Conrado in May
May: The South Atlantic Wakes Up
May is when Sao Conrado's winter season truly ignites. The average swell height jumps to 4-5ft (1.5m) and period climbs to 11.0s, giving the waves real long-period power. S swell dominates with 36%, SSE adds 25%, SSW contributes 9%, and SE adds 16%; importantly, the bigger category 5-8ft (1.5-2.5m) becomes common, with occasional waves over 8ft (2.5m) on the strongest S/SSW pulses. Ideal offshore winds register 51% as post-frontal N/NNW flow regularly grooms the surf between cold fronts. E/ENE winds are still around, but the more active storm track brings longer windows of clean S/SSE groundswell. Air temperatures cool to 22.2°C, water temp drops to 23.2°C, and rainfall is modest at 2.61mm/day. This is the beginning of the reliable season, with both size and quality lining up.
