October: First Winter Swell of the Season
October delivers the first real sign of winter. The average swell height is still modest at 0.9m (3ft), but the period jumps to 12.7s, the longest of the year, and longer-period W/WSW groundswell begins to show more often. WSW (32 percent) and SW (29 percent) dominate, with west swell at 21 percent and a growing WNW component (2 percent) hinting at the upcoming North Pacific season. Most days remain in the 2-3ft (0.5-1m) to 3-5ft (1-1.5m) range, but the longer period brings extra punch and better shape. Ideal winds improve to 62 percent, with the morning offshore N/NW flow becoming more reliable and the afternoon sea breeze weakening. Water temps are still warm at 17.2°C (63°F), air temps average 19.6°C (67°F), and rainfall remains low at 0.56 mm/day. October may not be the heaviest month, but it is the beginning of the good season.
