Conditions at Off-The-Wall in September
September: First Signs of Life as the Pacific Wakes Up
September is a turning point. The average swell remains modest at 1.7m (5.6ft), but the period climbs back to 9.2s and the percentage of NNW/NW energy starts to creep upward to 5.6%, while NNE (9.1%) and NE (18.1%) give the spot more raw material. The wind regime also improves: ideal-surfing conditions rise to 24%, with E (41.5%) and ESE (3.9%) offering a good share of offshore flow. ENE still dominates at 44%, so surface smoothness is not guaranteed, but the fall transition is underway. Water temps are warm at 26.7°C, air at 26.2°C, and rainfall begins to pick up again at 1.34 mm/day. The first strong NW groundswells of the season can already make Off-The-Wall glow before the calendar flips to October.
