Random Beach Break - surf spot statistics

Best Surf Season (October - March)

The northeast monsoon (Amihan) takes firm control over the Philippines from late autumn through early spring, funneling consistent ENE and NE swell toward this north-east facing beach. Average wave heights climb above 1.0m, peaking at 1.3m in January, with periods settling into the 9-10 second range. This is the prime window for size and power, but it comes with a catch: the prevailing nord-est winds blow directly onshore 70-88% of the time. However, when a cold front or low-pressure trough pushes through the South China Sea, winds veer to the SSW through W quadrant, delivering clean, offshore conditions. October stands out as the sweet spot – swell is building and offshore wind frequency hits an annual high of 45%.

Fair Surf Season (April - September)

As the Amihan weakens and retreats, the southwest monsoon (Habagat) becomes more influential. This pattern shifts the wind regime toward the south and west, dramatically increasing the percentage of offshore flow – from 24% in April to 37% in September. Unfortunately, the corresponding swell production drops off. Average heights range from 0.5m to 0.9m, and while periods remain respectable (8.6-9.9s), the waves rarely exceed 1.5m. The trade-off is consistent, glassy surf under mostly sunny skies. It’s a great time for groveling on small boards and longboards, with occasional pulses of longer-period energy from distant storms in the South Pacific or Indian Ocean.

Low Surf Season (June - August)

Mid-summer marks the absolute low of the swell calendar. Average wave heights bottom out at 0.5m, and the swell window is dominated by short-period east-northeast windswell with periods under 9 seconds. However, the Habagat is in full swing, producing offshore winds over 30% of the time. While the majority of days offer only knee-high, weak waves, there are fleeting moments of magic when a rare southerly or westerly groundswell slips through. Those days are few and far between, but for the patient surfer, clear-water, uncrowded sessions can be had.

September: Building Swell, Clean Winds

Spring begins to stir in the southern hemisphere, and the swell average inches up to 0.6m with a period of 9.9s – the longest yet. Swell from ENE (31.4%) and NE (21.1%) returns to dominance, while NNE (9.1%) and N (3.6%) start contributing from the north. Offshore wind frequency hits 37%, the second highest of the year. W (8.1%), WSW (7.8%), and SW (7.4%) are all well-represented. This is the month where the quality of conditions often outshines the quantity of swell. Clean, glassy, and increasingly punchy waves make September a hidden gem for this spot.
