September: First Real Promise of the Season
September is where the surf season at Mabuntok begins to wake up. The average swell height is still a modest 2ft (0.6m), but the average period climbs to 9.9s and the directional spread turns much more promising: ENE delivers 31.4 percent, NE 21.1 percent, E 19.2 percent, NNE 9.1 percent and NNW 4.3 percent. This is the first month in months where a meaningful chunk of the energy (NNE/NE/ENE) lines up with the spot's optimal window. The wind regime is still in Habagat mode; SSW/SW/WSW contribute solid offshore flow and ideal wind sits at 35 percent. That makes September a credible small-wave month: clean 2ft (0.6m) lines with the occasional waist-high set, plus a bit more period behind them. Rain is moderate at 6.0 mm/day, air temperatures stay at 27.8°C, and water remains warm at 29.4°C.
