September: The Biggest Average of the Year
September is the peak of the tropical storm season in the Eastern Pacific and the largest average swell month on the books at Puerto Madero. Wave heights average 4.9ft (1.5m) with a still solid 13.2s period, and the swell direction is beautifully aligned: SSW owns 69.2% and SW adds 21.9%, keeping the S/SSW/SW/WSW window above 99%. Stronger surf is common, with 18% of waves in the 5-6.5ft (1.5-2m) range and 2% in the 6.5-8ft (2-2.5m) class - and tropical cyclones can push things much bigger and heavier for days at a time. Ideal offshore winds remain around 52%, and the worst onshore directions contribute only 15.5% of the wind, so even as rain peaks at 13.07 mm/day, the surf holds up. Air temperatures average 27.8°C with a range of 24.5-31.6°C, and water temperature is 30.3°C. Be ready to trade some raindrops for some of the most powerful, lined-up waves of the year.
