September: The Autumn Transition Stirs
September marks the beginning of the end of summer. The swell height is still modest at 0.8m (2.5ft), but the period remains long at 13.6s and the direction mix has shifted to 44% SW, 27% WSW, and 24% SSW. You can feel the North Pacific becoming active again, even if the numbers don't show it yet. The wind, though, is still summer-like: ideal offshore flow exists only 7% of the time, and onshore SW/WSW flow still rules at 71%. Despite the average, there are occasional pulses of 1-1.5m (3-5ft) groundswell from SSW and WSW, and as the month wears on, those become more organized. Water is at its warmest of the year at 18.3°C (64.9°F), air temps hold at a pleasant 20.7°C (69.3°F), and precipitation remains rare. The autumn swell season is just around the corner, but bring your patience and your log for September.
