Cambodia’s two broad seasons
Cambodia has a tropical monsoon climate. The Ministry of Tourism broadly describes a wet season from May to October and a dry season from November to April. These are useful planning categories, not precise daily forecasts.
November–February
Cooler dry months
Generally the easiest period for long sightseeing days, road journeys and the coast. It is also a popular travel season, so major destinations can feel busier.
March–April
Hot dry months
Heat builds toward April. Begin outdoor visits early, slow the middle of the day and carry more water than you expect to need.
May–October
Wet and green months
Rain often arrives in intense periods rather than continuing all day, but prolonged rain does occur. Landscapes become greener and water levels rise.
Find the best month for your trip
Pick a month and what you most want to do. This is a planning guide based on Cambodia’s usual seasons, not a forecast, and conditions vary by region and year.
These ratings reflect Cambodia’s usual seasons and our own travel advice. Weather, road, sea and festival conditions vary by region and year, and we make no promise that they are accurate for your dates. Check a short-range forecast and current local advice before you go.

What changes by region
Siem Reap and the northwest
Dry months make temple circuits and rural roads simpler. Wet-season greenery, reflective pools and dramatic skies can transform Angkor, while slippery surfaces and storms require more caution.
Phnom Penh and central Cambodia
The capital can be visited year-round. Heat and sudden rain affect how much is comfortable on foot, so plan indoor museums, shaded stops and flexible meal breaks.
Kampot, Kep and the coast
The coast generally receives heavier wet-season rain and rougher seas. Boat and island trips are especially weather-dependent. Confirm conditions locally and accept cancellations when operators consider the sea unsafe.
Kratie and the Mekong
River levels change the appearance of islands, sandbars and currents. Dry months usually make cycling and road travel easier, while the wet season creates a broader river and greener countryside.
A practical month-by-month view
January–FebruaryTypically drier and relatively comfortable; popular for broad itineraries.
March–AprilHotter conditions; plan early starts and slower afternoons.
May–JuneTransition into the rains, with heat, storms and increasingly green landscapes.
July–SeptemberCore wet-season months; expect changing road, trail and sea conditions.
OctoberA transition month when rainfall and water levels may remain significant.
November–DecemberThe drier period returns and outdoor travel usually becomes easier.
Festivals, holidays and crowds
Cambodian public holidays and festivals can bring meaningful cultural experiences as well as busy roads, crowded attractions and reduced availability. Dates may follow lunar calendars or be officially confirmed closer to the event. Check current dates before building an itinerary around a festival.
December and January are also busy with Christmas and New Year travel. See our guide to international holidays in Cambodia for what is open, what closes and where to celebrate.
Nature and wildlife by season
There is no single best month for every Cambodian nature experience. Rain, temperature, river levels, road access, waterfalls and bird movement follow different rhythms—and conditions vary from year to year.
Generally drier months
Drier conditions often simplify long road transfers, forest trails and camping. Later in the dry season, heat, dust and smoke can become significant, while some waterfalls and minor waterways carry less water.
Hot transition
The hottest period can make exposed walking demanding. Plan early starts, carry more water than expected and keep midday free for rest. Storms may begin before a reliable wet-season pattern develops.
Wetter and greener months
Rain brings greener forest, fuller waterfalls and changing lake and river landscapes. It can also produce slippery trails, rough water, insects, delayed boats and roads that become difficult or temporarily unusable.
Tonlé Sap and the Mekong
Water level matters more than a simple wet-or-dry label. It changes boat routes, flooded-forest access, exposed river islands and the appearance of communities. Ask operators what the water is doing now. See also Tonlé Sap and the flooded forests.
Wildlife and birds
Species have different breeding, feeding and movement patterns. A reputable specialist can explain what is realistic during your dates without guaranteeing a target species.
A flexible checklist for nature trips
- Confirm road and boat conditions shortly before departure.
- Leave buffer time around remote transfers.
- Carry rain protection in every season.
- Protect electronics and medicine from water and humidity.
- Use local advice to adjust a route rather than forcing the original plan.
For what to bring, see the packing guide.
Weather planning principles
- Check a short-range forecast shortly before each travel day.
- Never treat a monthly climate summary as a guarantee.
- Protect yourself from sun even when the sky is cloudy.
- Keep electronics and documents dry during the wet season.
- Respect closures and local safety advice during storms or rough seas.
