Conditions at Hanalei Bay in November
November: Winter Locks In
November marks the true arrival of winter. Average swell height is 7-8ft (2.1-2.4m) and period extends to 11.6s, while NNW accounts for 15.1% and N, NNE and NW add another 21.1%. The mix still contains some NE and ENE trade swell, but the dominant signature is the North Pacific groundswell train, with long, organized energy aimed at the Hawaiian chain.
Winds are the main variable: ideal conditions drop to 35%, strong easterly trades still blow around 58% of the time, and onshore northern flow appears more often as fronts move through. When the trades ease and the wind clocks to a south or southeast direction, Hanalei is capable of excellent, heavy winter surf. Air temp averages 25°C (77°F), water is still warm at 25.9°C (79°F), and passing storms bring both rain and swell.
