Conditions at Sao Torpes in September
September: The First Autumnal Pulse
September marks the beginning of the surf recovery. Average swell rises to 1.4m (around 4-5ft) and the period stretches back to 10.6s, breaking the low-energy pattern of summer. NW still dominates at 55.4%, but WNW improves to 21.3% and W adds 5.2%, giving the beach more westerly energy. The percentage of 1.5-2.5m surf starts to climb, signaling the return of proper Atlantic groundswell.
Wind quality is better but still not great: ideal wind reaches 24%. NNW remains the dominant direction at 25.5%, with NW 17.8% and WNW 12.5%, yet the lighter wind speeds and longer swell periods allow for cleaner waves during the morning hours. Water temperature is at its warmest, around 18.1°C, air averages 21.3°C, and precipitation increases to 0.85mm/day. Keep an eye on the first autumn storm track; that is when the season comes alive.
