Mabuntok - surf spot statistics

Best Surf Season (October - April)

The North Pacific roars to life as the northeast monsoon establishes itself from October through April, delivering consistent swell to Mabuntok. Average wave heights climb to 1.0-1.3m with periods frequently in the 9-10 second range, offering punchy, powerful surf that lines up well on the north-northeast-facing beach. The trade-off is the persistent northeast wind that blows onshore most days, limiting clean conditions to occasional cold front passages or tropical disturbances that swing the breeze southerly. October and April stand out as transition months with a higher likelihood of offshore (S-SW) winds, making them prime windows for quality surf.

Fair Surf Season (May and September)

As the monsoon shifts, May and September deliver a balanced mix of moderate swell and improved wind conditions. Average swell heights drop to 0.6-0.7m, but periods stay solid at 8.9-9.9 seconds, providing fun-sized, rippable waves. The wind becomes more variable, with southerly (offshore) flow becoming frequent, especially in May when ideal wind percentages reach 38%. It's a great time for shortboards and step-ups when a decent groundswell shows up, though the overall energy is down from the winter peak.

Low Surf Season (June - August)

During the southwest monsoon, from June to August, Mabuntok experiences its smallest surf of the year. Average wave heights hover around 0.5m, slipping into the 'small, fun-sized' category. While the wind is reliably offshore from the S-SW quadrants (favoring the spot), the lack of strong North Pacific storm activity leads to weak, groveling waves. The average period remains decent (8.6-9.6s), so occasional longer-period swell from typhoons or distant storms can produce sneaky waist-high sets. Dedicated loggers and fish riders will find plenty of enjoyment, but those seeking heavy, firing surf should look elsewhere during these months.

May: Offshore Winds Arrive, Swell Drops

May brings a dramatic shift as the southwest monsoon sets in. Average wave heights fall to 0.7m with an 8.9-second period, meaning smaller, groveling waves. Swell direction is still ENE (62.7%) and E (27.4%), with a few NE (6.4%) pulses. The wind, however, is now predominantly offshore from the S and SW quadrants (S 4.3%, SSW 1.6%, SW 1.2%, WSW 1.6%, plus a lot of ESE and SE that cross-shore/offshore). Ideal wind conditions hit 38% of the time, making for clean, glassy mornings. Surfers on longboards and fish will love the fun-sized waves with perfect texture.
