Conditions at Figueira Foz in September
September: The Atlantic Wakes Again
September is the bridge back to autumn. Average swell height climbs to 1.5m (5ft) and the period lengthens to 10.5s. The swell direction still favours the NW at 44 percent, but WNW contributes a healthy 23 percent and the first proper W lines start appearing. Ideal offshore wind recovers to 31 percent as the synoptic pattern begins to change. NNW winds are still the most common at 35 percent, but they are lighter than in summer and more mornings bring clean conditions. Water temperature reaches its yearly peak at 17.9°C, air averages 19.8°C and precipitation stays moderate at 1.45 mm/day. September is a reliable sneaky-good month, especially when the first Atlantic lows kick up new WNW groundswell.
