Conditions at Ten Thousand Peaks in September
September: Monsoon Retreat Begins
September is a transitional month with mixed signals. Average swell drops to 4ft (1.3m), the period shortens to 9.3s, and the swell direction becomes even more WSW-dominant; roughly half of the recorded swell sits in the 3-5ft (1-1.5m) range, with a healthy chunk of 5-6.5ft (1.5-2m) energy. There is still plenty of wave to ride if you can find clean water.
The wind is beginning to shift. Ideal conditions rise to 18%, and while W, WNW and WSW winds are still common, the NE/E offshore flow starts to reappear more frequently. Rain decreases to 12.14mm per day, air temperature stays at 26.8°C and water temperature is 28.1°C. September still demands caution - the odd leftover monsoon surge can bring heavy rain and bad wind - but it is the first month where a real swell and a clean surface can occasionally meet.
