Conditions at Playa de San Juan in October
October: The North Atlantic Reawakens
October is when the North Atlantic and western Mediterranean low-pressure systems start breathing again. Average swell height begins to build at 1.3m (4ft) but the period jumps to 11.1s, placing the surf firmly in the powerful long-period class. The swell rose is led by a huge NNW peak at 40.9%, with N at 21% and NNE at 21.3%. That sets up a much more organised, clean wave direction for Playa de San Juan.
Equally important, the offshore wind window expands to 9%, the best since March. The southerly offshore window becomes more frequent, though NNE still leads at 37.3% and NE at 15.5%. Sea temperatures are still warm at 22.7°C and air temps average 22.3°C. October tends to deliver the first truly memorable surf days of the season, especially when a deep low brushes the Balearic Islands.
