Hanalei is a North Pacific winter wave, prime November through March and peaking in January; summer is mostly flat because the bay faces away from south swell. The engine is the Aleutian and Gulf-of-Alaska storm track, whose long-period north-to-northwest groundswell Kauai receives first among the main islands.
Where the swell comes from
Aleutian and Gulf-of-Alaska storms send the long-period north-to-northwest groundswell; Kauai is the northwesternmost main island and sits first in the firing line.
