Traveller notes on Koh Rong in November

Notes from nearby Phu Quoc (95 km away)

Koh Rong doesn't have its own notes for November yet — these are about Phu Quoc, close enough to share the season.

Regulars are specific this month splits into two real halves - early November still emerging from the rainy season with real showers and cloudy stretches possible, while conditions reliably improve from around mid-month onward into the warm, sunny weather the island is known for. Our row backs that hot, genuinely wet read, 31.5C reading as a scorching 36C, over 24.6C nights feeling 28C, with a substantial 138.8mm of rain across 18.2 days and humidity at 77 percent. Regulars are consistent this still counts as peak hotel season and one of the most popular windows to visit overall, any rain typically arriving in the evening rather than disrupting a full day. The sea sits at a bath-warm 30.1C. The record: 9.2 hours of sun, a 23.2 kph wind and AQI 45.

Other months in Koh Rong

Koh Rong's forum describes August as a genuine mixed bag - a decent mixture of sun and rain, with some stretches going several days rain-free and others turning genuinely miserable. One island worker described 15 straight days where it rained almost around the clock, which posters treated as an extreme outlier rather than typical. When rain does hit, it's usually a heavy hour-to-90-minute burst at night, early morning or mid-afternoon, and rough seas can cancel boat trips on the worst days. Opinions on visiting are genuinely split - some steer clear of Koh Rong entirely in August, while one experienced regular was confident sunny days still outnumber wet ones.

Forum posters place February inside Koh Rong's peak season, which runs roughly November through March and brings cool(er), dry conditions relative to the rest of the year - though posters are quick to add that the beaches themselves still run very hot and sunny by day, with water and a hat treated as essential rather than optional. The white-sand beaches and clear, warm water are repeatedly praised, with Sunset Beach singled out for its turquoise water. On the practical side, posters note some visitors worry about choppy seas delaying the ferry crossing even in the dry season, so building a buffer day into ferry-dependent travel plans is a common piece of advice.

    Calm dry-season water and a moonless night are what it takes; walk to a beach the resorts have stopped lighting and the water lights up where you move it. Nothing to see on a bright moon.
