September Sessions: The Sweet Spot of the Season

Let’s talk about September sessions. While most of the northern hemisphere starts
looking toward winter and watching the first leaves turn, West Sumatra is slipping
into one of the most magical windows of the year. The intense weather systems of
July and August—those pulse-filled months that deliver powerful surf and stronger
winds across the Mentawai Islands—begin to soften. What follows is a calmer, more
refined rhythm of weather that rolls in just before our traditional Sunda Straits season
and annual dry-dock period.

This is when the pace slows, the crowds thin, and the kind of playful, clean, and
genuinely enjoyable surf takes center stage aboard the MV Indies Trader III. During
September, the boat roams freely between the southern Mentawai Islands and the
Banyaks, slipping into zones others overlook and positioning you right where the
conditions come together best. With our annual Sunda Straits season approaching,
it’s an ideal moment for surfers of every ability level to be on board—equal parts
adventure and ease.

If you’ve ever watched Jack Johnson’s September Sessions, you already know the
vibe: warm water, glassy lines, good energy everywhere you look. And if you haven’t
experienced that feeling in person yet… well, September on the Indies Trader III is
exactly where it lives.
