Serangan - surf spot statistics

Best Surf Season (December - February)

This is the peak window at Serangan, driven by the northwest monsoon. Consistent offshore winds from the west and northwest deliver clean, groomed conditions 60-64% of the time. While the dominant swell comes from the SSW and SW—not the ideal E-SSE direction—the offshore flow transforms these long-period Southern Ocean groundswells into smooth, rippable waves. Expect average wave heights around 1.6-1.7m with periods of 12-13s, offering fun to pumping surf day after day.

Fair Surf Season (March & November)

These months represent the transition between monsoons. March still sees moderate offshore wind (48% ideal) with powerful 13.3s swell, but the trade winds begin to creep in. November marks the return of the monsoon with 31% ideal wind, after months of onshore slop. Wave heights average 1.6m, and while the swell direction remains south-oriented, the improving wind quality makes these months solid secondary targets.

Low Surf Season (April - October)

The southeast trade winds dominate from April through October, blowing directly onshore from the E-ESE-SE quadrant. Ideal wind plummets to 19% in April and further down to 0-3% from May through August. Although swell energy peaks during these months—averaging 1.9-2.2m with long periods over 14s from the deep south—the constant onshore wind wrecks wave quality, creating lumpy, choppy, and difficult conditions. Only rare light-wind windows or early mornings offer any refuge. September and October see a slight uptick in wind quality (3-13%), but conditions remain marginal.

January: Peak Monsoon Offshore Bliss

The northwest monsoon is in full swing, pumping consistent offshore winds from the west and west-northwest across the Serangan lineup. With 64% of the time offering ideal wind, this is prime season. Swell energy from the deep south—dominated by SSW (35.7%) and SW (47.4%) directions—pours in at an average height of 1.7m and a long period of 12.4s. The waves are clean, powerful, and often in the fun to pumping range. While the swell direction isn't perfect for this SE-facing beach, the offshore grooming more than compensates, delivering smooth walls and rippable shoulders.
