Meteo Koh Rong in marzo

March is inside Phu Quoc's dry high season - November to March on the strict reckoning, stretching to May on the generous one - and regulars call it a safe month: hot, sunny, blue sky, calm water. Our row gives 32.3C reading as 37C with a 29.4C sea. The island-specific advice is about which coast. The west is fine in March but is the side that turns rough and murky when the wind gets up or the wet season arrives; the east is more sheltered, and Khem Beach in its bay is the one they name for reliably clear, calm water. Our row still counts 14.7 precipitation days carrying only 50.7mm, which is the brief tropical shower rather than a wet month. The record: 24.2C nights, 11 hours of sun and a 21 kph wind.

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.
