September: The First Spark of Autumn
September is still a low month, but autumn is starting to stir. Average wave height lifts to 2ft (0.6m), the period to 4.3s, and ideal wind improves slightly to 8%. The south-swell window is active, with WSW (15.0%), S (14.4%), SW (11.9%), SSE (10.6%) and SSW (8.9%) feeding the beach, and the first WSW pulses occasionally reach 5ft (1.5m) as the Mediterranean re-awakens. Wind is mixed: early September still feels like summer with SSE (9.6%) and SE (8.3%) onshore breezes, but late in the month NNE (7.3%), NE (7.2%) and NNW (7.1%) start making offshore moves. Water temperature remains warm at 23.1°C, air temp averages 21.9°C, and rainfall climbs to 2.67mm/day. Keep an eye on the forecast; the last week of September can deliver the best surf since spring.
