Conditions at Supertubos in September
September: The Atlantic Reawakens
September is the beautiful transition month. The ocean noticeably picks up: average swell height climbs to 5.6ft (1.7m) and periods lengthen to 10.5s - a major step up from the mid-summer snooze. The swell direction is still largely from the NNW (33.1%) and NW (33.5%), but a growing WNW (15.5%) component begins to deliver more classic ground swell. Wave heights are mostly in the 1-2m range, with some 2.5m days possible as late-season storms fire up. Wind quality improves to 37% ideal, and although the NNW thermal is still present (40.4% of wind), it begins to relax enough at times to allow clean easterly offshores. The water is still warm at 18.7°C and air temperatures are pleasant. This is the hidden gem month for Supertubos: the crowds start to empty and the waves regain that familiar punch.
