Conditions at Praia de Monte Gordo in September
September: The Season Readies
The first signs of autumn arrive with September. The average swell creeps back to 0.5m (1.6ft), period lengthens to 5.8s, and the percentage of ideal wind inched to 18%. More importantly, the swell direction matrix begins to favor the SE/SSE corridor: SE accounts for 16.0% of wave energy, with 9.1% in the 0.5-1m (1.6-3.3ft) class and 1.3% in 1-1.5m (3.3-4.9ft). Adding SSE (7.0%), S (3.9%), and SSW (3.9%), the optimal swell window reaches just under 31% - a noticeable increase from summer. Occasionally, the first autumn low in the Atlantic sends a modest long-period swell toward Iberia, giving Monte Gordo a couple of clean, chest-high days.
Winds are still summery, with NNW at 25.8%, NW at 10.0%, and the ideal wind percentage only 18%. Air temp remains warm at 22.3°C, water stays at 21.0°C, and rainfall starts to increase with 0.69mm/day. The window is small, but the first legitimately surfable northwest groundswell of the season can show up this month.
