Conditions at Lafitenia in September
September: The Autumn Wake-Up
September is the month when Lafitenia starts to wake up from its summer sleep. The average swell height climbs to 1.1m (3.6ft) and the period stretches back to 10.6s, which is enough to make the waves start feeling punchy again. The direction profile remains excellent, with NW at 53.8%, WNW at 33.3%, and NNW adding 8.3%. More importantly, the number of 1-1.5m (3.3-5ft) waves jumps, and the first true groundswell pulses begin to show up in the 1.5-2.5m (5-8ft) range.
Ideal wind frequency rises to 27%, as the Azores High weakens and Atlantic lows start to approach the coast. You still get warm summery air at 19.0°C and the water is still a pleasant 21.0°C, which means you can often surf in a thinner wetsuit or even a spring suit. Rainfall averages 2.59mm/day. September is a shoulder month with two faces: plenty of small-to-fun waves, but also occasional early-autumn swells that deliver clean, lined-up surf with far fewer crowds than the winter peak.
