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.

August: Summer Consistency, Still Small

August sees similar conditions to July, with 0.5m average swell and a solid 9.6-second period. Swell directions are a mix of E (35.3%), ENE (23.7%), and increasing contributions from ESE (13.4%) and SE (8.8%). The wind remains offshore to cross-offshore: S (14.2%), SSW (8.0%), SW (7.9%), WSW (11.1%), and W (13.2%) dominate. Ideal wind percentage rises to 33%. The surf is small but clean, with occasional pulses from distant storms or typhoons that can push waves into the fun 1m range. Loggers and fish will be happy, but don't expect barrels.
