Conditions at Riptides in September
September: Late-Season Gems on the Monsoon Edge
September keeps much of August's goodness alive as the monsoon begins to loosen its grip. Average height is still a solid 4ft (1.2m), and the period holds at 9.0s. The swell is again strongly SSE at 35.4 percent, with south at 21.4 and SSW at 13.5, so Riptides continues to see plenty of direct, wrap-friendly energy. Wind-wise, west is the big player at 31.6 percent, WNW adds 25.5, and WSW contributes 17.8; ideal wind sits at 50 percent. That is a recipe for clean, glassy conditions and quality reef waves through the middle of the day. Most sets arrive in the 3-5ft (1-1.5m) range, with occasional 5-6.5ft (1.5-2m) pulses from the WSW/W spectrum. As the month progresses, the NE monsoon starts to creep back, but September should still deliver plenty of fun. Air temps drop to 27.5°C, water temperature is 29.0°C, and rainfall remains high at 6.08mm/day.
