Pogoda Preăh Sihanŭk — styczeń

Forum posters consistently call January one of the best times to visit, squarely inside the November-March dry season and the island's peak season as a result - clear water, reliable sunshine and calm seas are the norm. One visitor specifically noted that despite weather apps repeatedly forecasting storms throughout their stay, the reality was mostly sunny with only the odd brief downpour, describing conditions as close to perfect. Posters recommend booking accommodation ahead given the popularity of this window, and generally rate Phu Quoc as a more kid-friendly beach option than mainland alternatives like Mui Ne thanks to its calmer January seas.

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.
