Conditions at Seal Beach in October
October: Autumn Returns
October is where the season starts to turn. The average swell height remains a modest 2-3ft (0.8m), but periods are long (13.4s) and the direction mix has shifted enough to matter: SW 42.2%, WSW 29.8%, SSW 18.5%, and W 8.8%. More importantly, the wind distribution changes dramatically. Ideal conditions occur 23% of the time - a huge jump from summer - as NE (6.9%), NNE (2.7%), and N (0.7%) offshore flows make a comeback. The ocean surface is still choppy on many days, but the early morning clean windows become longer and more frequent. When a stronger North Pacific storm sends a westerly swell in the 3-5ft (1-1.5m) range, the SSW-facing beach gets a genuinely fun, rippable day. Water temp remains warm enough for a thinner wetsuit (17.7°C), air temp averages 19.3°C, and rainfall stays low at 0.43 mm/day.
