Conditions at Playa Marbella in September
September: Big Swell, Blustery Chaos
September brings the most extreme combination of conditions all year. Swell direction could not be better - SSW at 66.7% and SW at 28.8%, with visible portions of 1.5-2m (5-6.5ft) in both quadrants and 1.9% of SW waves reaching 2-2.5m (6.5-8ft). Average heights peak at 1.5m (5ft). Yet the ideal-wind index crashes to 38%, the lowest of the year, as the ITCZ settles directly overhead and westerly/southwesterly onshore wind components (WSW 7.9%, SW 7.9%, SSW 8.5%, W 6.8%) work against the beach's west-southwest orientation. Heavy tropical downpours (8.75mm/day) keep the air humid and the surface bumpy. Keep an eye on the satellite: the rare window of offshore flow and a strong Southern Hemisphere groundswell is pure Playa Marbella magic.
