Conditions at Vila Franca do Campo in September
September: The Autumn Switch Flips
September is one of the most exciting transition months on the calendar. The Azores High is still influential, but the North Atlantic storm track is beginning to sag south again, and the numbers show it: average open-ocean swell climbs back to around 5.5ft (1.7m), with periods stretching to 10.4s. NNW swell still leads at 25.3%, followed by NW at 15.1% and WNW at 9.9%, but the SE/SSE/S/SSW window begins to open more often as early-season lows interact with the mid-latitude flow, even though it remains under 3%. Offshore winds are still generous at 41%, with NNW (11.0%) and NNE (7.7%) leading the ideal sectors, so the southern pulses that do arrive are often clean. Water temps are still summer-like at 23.0°C, air temps average 22.3°C, and rain increases slightly to 1.68mm/day. A September south-swell day with offshore flow can feel like the best surf of the year.
