Meteo Koh Rong in aprile

Phu Quoc-forum threads on April weather describe it as sitting right at the edge of the low-rain season, still officially inside it but with humidity climbing and the occasional scattered storm creeping in as the wet season approaches. Posters are consistent that any given shower runs brief rather than disruptive, and the month keeps its reputation as pleasant for beach time - warm, sunny, with gentler crowds and prices than true peak season. The record actually runs wetter than most forum threads suggest for a nominally low-rain month, a reminder the wetter transition can arrive earlier in a given year than the calendar label implies. The record: 33C days feeling like a punishing 39C, 25.2C nights, a notably high 107mm across 18.4 days, 77 percent humidity, a 31.2C sea and 11.1 hours of sun.

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.
