Conditions at Telescopes in September
September: Late Season Power Holds
September is still deep in the dry season. Ideal wind is 56%, and the SE (23.7%) and SSE (22.3%) trade winds remain dominant. Average height eases only slightly to 4-5ft (1.3m) with a 14.2-second period, meaning reliability stays high. S and SSW swells are nearly split at 45% and 52%, keeping strong south groundswell in the water. As the month progresses, the monsoon dynamics begin to shift, so the clean windows can become a bit more inconsistent, but there are still plenty of excellent sessions. Rainfall starts to creep up at 9.26 mm/day, and water temperature settles at 28.9°C. In September, the reef still handles long-period south energy with ease, especially when the offshore trades hold through the morning.
