Conditions at Pencit Reef in May
May: Clean but Small
May signals the start of the low season. Average swell height drops to 0.8m (2.6ft) and period is 9.1s. The swell is almost entirely from the ENE (66.7%) and E (14.4%), with smaller NE contributions. Most wave heights are in the 0.5-1m range - small, fun-sized, groveling waves that only light up the inside sections of the reef during the mid-tide push.
The wind regime flips: ideal surf wind from S, SSW, SW, and WSW now occurs roughly 30% of the time, with many light E/SE sea breezes in between. That means plenty of clean, smaller days and a few morning windows with true offshore flow. The trade-off is that the power is missing. Overhead days are rare, and the average period is only mediocre. This is the time to work on your grovel game or enjoy longboard-style lines across the reef. Air is warm at 28.3°C, water is 29.4°C, and rain is low at 4.9mm/day.
