Conditions at Brookings in September
September: Autumn's First Roar
September is the bridge back to winter. Average heights creep up to 6.2ft (1.9m) and average periods stretch to 10.5s as the first real groundswell pulses start showing in the Pacific. The directional spread still favors NW (26.3%) and WNW (24.0%), with NNW (14.6%) and W (11.6%) behind them. Wind remains favorable 54% of the time, with NNW (29.3%) and NNE (11.9%) leading the way; the true N/NE offshore days become noticeably more common as high pressure begins to break down. Water temp reaches its annual peak at 11.8°C, air temps average 15.2°C, and rain is still light at 1.07 mm/day. September often sneaks in the best quality-to-size ratio of the year: not too big, not too wild, and still clean.
