Conditions at Faja da Caldeira de Santo Cristo in September
September: The Calm Before the Autumn Roar
September is a transition month and one of the best bets for clean, user-friendly surf. Average swell heights edge up to about 3.5-4ft (1.1m), periods stretch back to 9.2s, and the S/SSW/SW window holds around 11% of the wave rose. Much of that southerly energy is in the 1.5-5ft (0.5-1.5m) range, but the longer period means a little more push on the face. Remnants of tropical systems or early-season Atlantic lows can occasionally throw a stronger S/SW groundswell toward the islands, providing a welcome late-summer bonus. The background NW, WNW and WSW swells remain dominant, though, so wave selection gets crucial.
Winds are still favourable: N/NNE/NE/NNW flow sits near 25% of observations, with ideal conditions 20% of the time. Water temperature is still warm at 22.6°C, air temperatures are mild at 21.9°C (min 17.7°C, max 25.9°C), and rainfall increases to 2.21mm/day. September offers the tantalising combination of warm ocean water, clean summer breezes and the first real pulses of autumn swell.
