Conditions at Topanga in October
October: Fall Back Into Rhythm
October is the first month that genuinely feels like a return to form. Average period jumps to 12.9s, the highest of the year, while the average swell height settles at 2-3ft (0.7m)-a low number that masks the power of the long-period west and west-southwest groundswell pulsing through. Ideal offshore wind reaches 48%, with N, NNE and NW making up a healthy share. W swell still carries 16.4% with 5.5% in the 3-5ft (1-1.5m) band, while WSW and SW combine for 73.7% of the total spectrum. Water temp remains warm at 17.1°C, air temps average 19.6°C, and only 0.56mm/day of rain means autumn is still dry. The first significant North Pacific swells start to overlap with the leftover summer south-swell energy, and Topanga can produce some classic lined-up days.
