Conditions at Margara in September
September: The Fall Turnaround Begins
September is the start of the transition back to better surf. The average wave height is still modest at around 4.5ft (1.3m), and the period remains short at 6.1s, but the direction mix improves. ENE drops to 50.2%, NE climbs back to 27.6%, and NNE reaches 10.2%, with some N and NNW energy reappearing. Most waves are in the 3-5ft (1-1.5m) range, though there are a few 5-6.5ft (1.5-2m) sets from the northeast. Offshore wind is ideal 48% of the time, the highest of the summer-to-fall months, so clean conditions are much more common. Air temperatures average 27.8°C, water is 29.2°C, and rainfall increases to 5.74 mm/day. Keep an eye on late-season tropical systems; even if their swell direction is not perfect, they can briefly pump size into Margara.
