Pogoda Preăh Sihanŭk — kwiecień

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.

Sihanoukville forum regulars describe August as genuine monsoon season, with rain that can hit overnight, early morning or mid-afternoon and, when it does, comes down hard for roughly an hour before clearing. One traveler who spent two weeks there in August said it only rained a handful of times, always torrential but brief, and had more sunny days than wet ones overall. The bigger risk isn't the rain itself but rougher seas - a few posters mentioned island boat trips to Koh Rong getting cancelled on choppy days, so it's worth building a spare day into any island-hopping plan.

Forum posters describe February as comfortably inside Cambodia's dry season, with beaches around Sihanoukville generally clean and calm this time of year. Posters are candid, though, that the country's tropical climate means even peak dry season isn't fully rain-free - localized afternoon or evening showers and brief thunderstorms remain possible, following a common daily pattern of a sunny morning giving way to clouding and rain later in the day. Posters treat this as a minor, short-lived interruption rather than a reason to avoid the period, with February still ranking among the better months for beach time on this coast.
