Conditions at Aterro in June
June: Grovel Season Begins
June brings Aterro into the summer groove: average swell 5ft (1.5m) and period 9.2 seconds, signalling a shift to average-punchy windswell. Direction remains favorable - NW (37.6%), WNW (23.9%) and NNW (22.7%) make up the bulk - but most of this is low-energy windswell and small background swell rather than true groundswell.
The wind is the main issue. Ideal conditions are scarce at 15%, as the thermal gradient stacks up NNW winds at 37.6%, while NW (14.8%) and WNW (6.6%) add direct onshore push. Only the E/SE and S/SSW directions, totalling around 15%, bring workable corners. Water temp climbs to 16.9°C, air to 18.5°C, and rainfall dries up to 0.97 mm/day. Time to dig out the grovel board.
