Conditions at Pencit Reef in September
September: Cleanest Shoulder Surf
September is the first month of the year where swell size and favorable wind genuinely overlap. Average wave height is still only 0.8m (2.6ft), but the period climbs to 9.5s and the swell rose shows a distinct re-emergence of the NE and NNE directions: NE 27.1%, ENE 22.7%, and NNE 11.4%. Some 1-1.5m (3-5ft) waves appear with greater regularity, especially from N/NE swell events that drift in from typhoons or distant frontal systems.
The wind is the best of the entire year for Pencit Reef. With 57% ideal offshore flow, S/SW/W winds are common and the monsoon surface chop is often absent. The combination means numerous glassy, rippable sessions on a still-modest swell. It will not rival winter's size, but average quality per wave is hard to beat in September. As the month progresses and the ocean transitions toward the northeast monsoon, the trend points up. Water is 29.5°C; rainfall is 6.3mm/day; air temps remain warm and tropical.
