Conditions at Playa de la Canteria in September
September: The Autumn Switch Begins
September is when the Atlantic begins to stir again. The average wave height is still modest at 1.2m (4ft), but the average period climbs back to 9.5 seconds, signalling the return of longer-period energy. The swell window is beautifully balanced: N at 30.5 percent, NNE at 31.9 percent, and NNW at 31.1 percent, with the best size clustering in the 0.5-1m and 1-1.5m ranges. This is not yet winter-sized, but the directional consistency is there. Wind remains mostly onshore - NNE at 50.3 percent, N at 16.2 percent, and NE at 9.9 percent - and the ideal offshore S/SSW/SW/WSW flow is only around 4 percent of the time. A few early autumn fronts can bring the first real groundswell of the season, and if you catch a south wind behind one of them, the beach can produce clean, fun waves. Water temperature is still warm at 23.0°C, air temps average 22.9°C, and precipitation starts to creep up to 0.20mm/day.
