Conditions at Ilha dos Lobos in October
October: The Tradewind Build
October is a transition month and a frustrating one for wave quality at Ilha dos Lobos. Swell heights remain generous at 1.7m (5-6ft), but average period drops to 8.6s and favorable wind plummets to 23%. The swell distribution is dominated by ENE (22.2%) and E (20.5%), with ESE (14.1%), SE (12.6%) and SSE (11.7%) playing secondary roles. The E/ENE windswell is plentiful but often lacks the organization of true winter groundswell.
Winds are mostly from the NE/ENE quadrant -- NE (23.4%), ENE (14.1%), NNE (12.0%) -- which puts the beach in a lumpy, onshore regime for much of the month. The bright side is that cold fronts still reach southern Brazil often enough to back the wind around to W or SW for a day or two, creating clean windows on otherwise messy seas. Air temps warm to 17.8°C, water temp to 18.8°C, and rainfall averages 5.1mm/day.
