Meteo Koh Rong in luglio

Phu Quoc's forum calls July rainy season but not the peak of it, with rain most days though rarely an all-day washout, and rougher seas particularly on the island's west side. Regulars note conditions vary a lot by luck and by which coast you're on, with the calmer southeast side a better bet, and several suggest waiting for October or November if reliable beach weather matters more than the trip dates.

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.
