September: The Peak of Size and the Hurricane Wildcard
September is historically the climax of surf size at The Ranch. Average wave height reaches 1.7m (5.6ft), the highest of any month, with an average period of 13.0 seconds. SSW still dominates at 58.9 percent, but S and SW are both active, and the distribution skews bigger: roughly equal parts 1-1.5m (3-5ft) and 1.5-2m (5-6.5ft), while 2-2.5m (6.5-8ft) energy appears from S, SSW and SW. Even the first hints of 2.5m+ (8ft+) swell can show up when a hurricane or major southern hemisphere system aligns perfectly.
Wind doesn't fully cooperate - ideal conditions are 37 percent, with N/NE offshore flow at 24 percent and onshore S/SW at 43 percent. September is also the wettest month of the year, with 7.65mm/day of rain, warm air at 26.3°C, and water at a very warm 30.1°C. The Ranch in September can be a powerful, heavy beast; the key is threading the needle between tropical disturbances to catch the offshore wind windows behind departing low-pressure systems.
