Traveller notes on Sihanoukville in November
Notes from nearby Phu Quoc (65 km away)
Sihanoukville doesn't have its own notes for November yet — these are about Phu Quoc, close enough to share the season.
Regulars are specific this month splits into two real halves - early November still emerging from the rainy season with real showers and cloudy stretches possible, while conditions reliably improve from around mid-month onward into the warm, sunny weather the island is known for. Our row backs that hot, genuinely wet read, 31.5C reading as a scorching 36C, over 24.6C nights feeling 28C, with a substantial 138.8mm of rain across 18.2 days and humidity at 77 percent. Regulars are consistent this still counts as peak hotel season and one of the most popular windows to visit overall, any rain typically arriving in the evening rather than disrupting a full day. The sea sits at a bath-warm 30.1C. The record: 9.2 hours of sun, a 23.2 kph wind and AQI 45.
Other months in Sihanoukville
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.
