Ingonish Beach • Statistics for September

September: The Autumn Door Creaks Open

September is a teasing shoulder month at Ingonish. The average swell climbs to 3.5ft (1.1m), period is 7.0s, and the direction mix is encouragingly varied: NNW and NW combine for 17.5%, while S/SSE/SSW contribute another 23.5%, mainly as short-period windswell. More importantly, September is prime hurricane alley in the North Atlantic, and this is when tropical swells can sneak up the East Coast and wrap into the Cape Breton shoreline with E/SE energy that dwarfs the 1.1m average. The wind remains cleanly offshore for much of the month, with ideal conditions holding at 46% and WSW, W and NW all strongly represented. Water is still warm at 16.6°C and air temps average 14.6°C. If you pick the right September swell window, you can score clean overhead waves on an east-facing beach without needing a winter hood and gloves. If no tropical-track system materializes, the surf is still mostly small and average, a bridge between summer lulls and autumn power.
