November: Offshore Winds Return, Winter Swell Takes Shape
November is a transitional gem. East energy remains strong, with ENE at 18%, E at 16%, and ESE at 10%, while W-direction swell climbs back to 13% as winter storms spin up in the Sea of Japan. Average height stays at 5ft (1.6m) and period is 7.7s. The big improvement is wind: W at 23% and WNW at 5%, plus NW and NNW, give offshore flow about 31% of the time, pushing ideal wind back to 20%. The result is more clean, groomed sessions, with winter's bigger W/NE swells starting to mix with residual E/ESE groundswell. Water temperature cools to 21.6°C, air averages 17.7°C, and precipitation drops to 4.0mm/day, making November one of the most reliable surf months of the year.
