Conditions at Chatarra in September
September: The Hurricane Swell Wildcard
September is a true wildcard. On average, surf size dips to 2-3ft (0.6-0.9m) with a 6.1s period, and the background direction is still ESE (48.1%) and E (34.3%). But this is the statistical peak of the Atlantic hurricane season, and the presence of SE (11.3%) and a growing SSE/S component tells you the tropical conveyor belt is active. A single cyclone passing through the region can easily turn Chatarra from marginal to firing - if the track puts even a moderate N or NW fetch into the beach.
Wind conditions are less brutal than mid-summer, with E at 31.8%, ESE at 26.7% and SE at 10.6%. Ideal offshore wind improves to 35%, so the break has more clean and glassy moments even without a hurricane. Rain is heavy at 6.02mm/day, water is 29.2°C, air is 27.8°C. The lesson for September: follow the hurricane models, keep the board ready, and do not sleep on the pre-storm swell window.
