Weather and Climate
Situated at 10 degrees north latitude, Sihanoukville sits in a warm, tropical marine climate. There are three distinct seasons: the cool and dry season from mid-November to February, the hot and dry season from February into the end of May, and the rainy wet season from June into November.
Cool and DryThe cool and dry season from November into February is considered by many to be the best time to visit, and is indeed the peak season for holiday-makers. The days don't see the extreme heat of the hot season, and the nights get quite cool (by tropical standards). The weather mid-day is nice and warm, and the nights bring a pleasant cool. The temperature will rarely dip below 20°C (68°F), nor rise much higher than 28°C (82°F).
Hot and DryThe hot and dry season in the late spring brings very warm temperatures and little rain. February and March bring perfect beach weather: sunny skies, rainless days and nice breezes - but as April comes around, things heat up, as temperatures can rise as high as 36°C (97°F), but rarely much higher than that. The sun's intensity (remember, the tropics receive much more direct sunlight than the temperate regions like Europe and America) and relative humidity can make you sweat like Mike Tyson at a spelling bee. Thankfully, an abundant sea and abundant cold beer awaits you wherever you go.
The Rainy SeasonBeing in the tropics, rain is expected. During the summer months comes the monsoon rains. The rains replenish the rice fields and bring beautiful greenery to the surrounding hills. Fortunately, while rain can be a daily occurrence, it rarely lasts the entire day. Most the day can still be spent enjoying the warning rays of the sun, but expect rain and perhaps a thunderstorm in the afternoon or evening. If you're going about during this time, an umbrella is a wise investment. High temperatures this time of year hover around a moderate 30°C (86°F). During September and October, the air temperature decreases and the nights can turn quite cool (into the low 20's).
