November: Winter Chaos with Classic Windows
November is where winter truly takes hold. Average swell height rises to 2.4m (7.9ft) and average period reaches 12.0s, delivering powerful, long-period groundswell from frequent Atlantic lows. The dominant swell direction is NNW at 23.8 percent, with NW at 15.3 percent, WNW at 6.6 percent, NNE at 8.7 percent and N at 6.6 percent. A substantial portion of the energy falls in the 1.5-2.5m (5-8ft) range, and the over-2.5m (8ft+) category is more present than in October, so expect genuine winter waves. Wind patterns remain mixed; NE and NNE together account for around 32 percent, but the SSW-SW-WSW-W offshore sector is active enough to hold ideal conditions at 19 percent. The trick in November is timing the post-frontal windows, when west/southwest winds clean up a fresh, powerful groundswell. Air temperatures cool to 15.7-23.5°C, water temperature drops to 21.2°C, and precipitation becomes more persistent at 1.51mm/day. This is serious surf month; bring confidence, a sturdy shortboard and the right wetsuit for a long session.
