Conditions at Praia dos Ingleses in September
September: Autumn's First Pulse
September is where the Atlantic starts to show signs of life. Average size climbs back to 1.1m (3-4ft) and the mean period jumps to 10.4s, nudging back into the long-period range. WNW (42%) and NW (39%) still rule, but W (11.5%) and WSW (3.1%) increase their share compared to midsummer. The first real groundswells of the season begin to arrive from low pressures developing east of the North American seaboard, and occasionally a Cape Verde tropical system can toss in a rare southern pulse.
Ideal wind frequency rises to 42%. NNW (29.2%) and NW (10.4%) remain common, but the decreasing strength of the coastal jet means more semi-clean days. Water is still warm at 16.8°C, air averages 19.2°C, and rain remains modest at 1.92mm/day. This is one of the best late-summer windows for combining warm water and increasing swell.
