October: First Autumn Hints Arrive with South-Swell Relics
October is a true transition month. The average wave period stays long at 13.4s, while average height holds at 0.8m (2-3ft). Swell directions are still tilted toward the southwest, with SW at 42.2%, WSW at 29.8% and SSW at 18.5%. Late-season hurricane energy can mix with the first North Pacific groundswell pulses, creating some surprisingly clean southwest lines when the timing is right.
The wind pattern begins to shift in your favor. Ideal offshore flow jumps back to 20%, and while W at 21.4% and WSW at 15.0% still appear, the morning N to NE breezes become more common after summer. Water temperature is a pleasant 17.7C, air temperature averages 19.3C, and rainfall rises to 0.43 mm/day. October is when Newport starts to turn back on, especially during the first true autumn swell events.
