Conditions at Wilderness in September
September: Spring Uncertainty Arrives
September is a genuine transition month. The offshore wind share falls to about 18%, with NNW at 7.7%, and the E/ESE flow begins to rebuild as the sun gets stronger. The average wave statistics are still flat, so the daily surf will be highly dependent on individual weather systems. Early-season cut-off lows can still fire up S/SSW swells, but the afternoon sea breeze becomes an increasing problem. Water temperature rises to 16.0°C, air averages 15.3°C, and precipitation is 1.13 mm/day. This is a month for smart surfing: pick the days with a high-pressure cell positioned to the southeast and a cold front approaching from the southwest.
