Conditions at Kincardine in September
September: Autumn's First Real Swell Pulse
September brings a genuine step up in energy. The average wave height jumps to 2.5-3ft (0.8m) and the average period to 4.2s, while the wave rose starts to look more like a surf forecast than a summer lake report. NNW (18.3%) remains dominant, but S (12.7%), SSW (11.2%), NW (8.0%) and a healthier WSW/W/WNW cluster give Kincardine more of the directional spread it needs. Some 0.5-1m and 1-1.5m bins fill in, creating more frequent counts of fun-sized, groveling waves.
Early-autumn low-pressure systems begin to cross the Great Lakes, and the wind field shifts. S and SSW winds still dominate, but ideal surf wind sits at 4% and the increasing frequency of westerly swell ahead of cold fronts shows promise. Air temperature averages a mild 17.1°C with 2.56 mm/day of precipitation, so autumn is returning to the lineup just as the surf begins to wake up.
