October: The North Pacific Wakes Up
October is the transition back to winter. Average wave height climbs to 6ft+ (1.9m), period lengthens to 10.8s, and the swell distribution starts to diversify. While ENE remains the top source at 29.1%, the combined NE/NNE contribution reaches nearly 32%, with a healthy NNW pulse (9.0%) beginning to filter around the islands. These are the first longer-period groundswells of the season, and any of them can produce clean overhead sets at Kealia.
The wind regime is still trade-heavy - ENE at 42.7% and E at 21.1% - but ideal offshore winds tick up to 7%. That is not huge, but you can start to count on a few meaningful clean windows each month. The arrival of a low-pressure system in the Gulf of Alaska can swing the wind to the west and line the swell up perfectly. Water temp is 26.6°C, air 25.7°C, and rain increases slightly to 1.94mm/day. October is a hopeful month.
