Best Time to Visit Cambodia

Cambodia is tropical and warm throughout the year, with two broad seasons. For most travellers, the cool and dry period from November to February offers the most comfortable weather for temple visits and beach time.

Cambodia is warm throughout the year, but the character of a trip changes noticeably with the seasons. There is no single perfect month for every traveller. The most comfortable weather brings the largest crowds, while the wetter months reward flexible visitors with green landscapes, dramatic skies and quieter temples. Decide first whether your priorities are long temple days, beach time, photography, festivals, wildlife, low prices or uncrowded travel, then choose the season that best supports them.

Cambodia’s climate at a glance

The country has a tropical monsoon climate with a broadly dry season and wet season. November through February is usually cooler and drier. March through May remains mostly dry but becomes much hotter. From June through October, the southwest monsoon brings higher humidity and regular rain. Weather varies by region and year, and a rainy-season day often includes a heavy afternoon shower rather than continuous rain from morning to night.

Temperatures are commonly warm even in the coolest months, so lightweight breathable clothing remains useful. Mountainous areas such as Mondulkiri can feel cooler after sunset, while Phnom Penh and lowland temple sites retain heat. Check a short-range forecast shortly before each transfer, but avoid treating a single rain icon as proof that an entire day will be lost.

November to February: cool and dry

This is the classic high season. Mornings are relatively fresh, humidity is lower and clear days suit Angkor, Phnom Penh walking tours and the southern coast. It is the easiest period for travellers who want a full sightseeing schedule without extreme heat. It is also the busiest and often the most expensive, especially around Christmas, New Year and Lunar New Year travel periods.

Reserve popular hotels, guides, long-distance transport and island accommodation in advance. Start major temple visits early even in cool weather, both for softer light and fewer tour groups. Less famous ruins, countryside excursions and a midday rest can balance crowded headline sites. Browse our Cambodia attractions guide to mix iconic places with quieter alternatives.

March to May: hot and dry

These months can be intensely hot, with afternoon temperatures frequently reaching the mid-thirties Celsius or higher. Clear skies remain common, but a fast-paced itinerary becomes tiring. Plan temples, markets and outdoor walks from sunrise until late morning, return to shade or a pool during the hottest hours, and resume near sunset. Carry water, use sun protection and choose accommodation with reliable cooling.

April brings Khmer New Year, one of Cambodia’s most important celebrations. Families travel home, pagodas become lively, some businesses close and transport fills early. Visitors can enjoy decorations, games and community events when they plan respectfully and patiently. Confirm opening hours, reserve transfers and understand that water play may be part of public celebrations in some places.

June to October: green and wet

The wet season transforms rice fields and forests into vivid green landscapes. Waterfalls strengthen, moats and reservoirs fill, and cloud patterns create excellent photography. Visitor numbers are generally lower, which can make Angkor and provincial destinations feel more spacious. Accommodation deals are easier to find, although some beach and island services reduce schedules.

Rain is often concentrated in forceful showers, with usable weather before or after. Carry a compact rain jacket, waterproof important documents and choose quick-drying footwear. Unpaved roads can become muddy and rural journeys may take longer. Keep one flexible half-day in the itinerary so an outdoor activity can move when necessary.

Tonlé Sap expands dramatically during the wet season, changing life around floating and stilted communities. Boat access and scenery can be better at higher water levels, though responsible visits should respect residents’ privacy and support community-conscious operators. Consider an API-listed experience from our Cambodia experiences page rather than an intrusive stop.

Beaches and islands

The most dependable beach weather usually falls in the dry season, particularly from late November through April. Seas are calmer and boat schedules more reliable. During the monsoon, rough water can delay ferries and some island businesses operate reduced hours. Travellers visiting from June to October should keep their mainland return flexible and avoid connecting an island boat directly to an international flight.

Kep and Kampot can still be rewarding in wetter months, with atmospheric river scenery, pepper farms and fewer visitors. Sihanoukville is primarily a gateway to the islands, while Koh Rong and Koh Rong Sanloem provide different beach settings. Compare transport timing in our Getting Around Cambodia guide.

Festivals worth planning around

Khmer New Year normally takes place in mid-April. Pchum Ben, the ancestors’ festival, falls in September or October according to the lunar calendar. Bon Om Touk, or the Water Festival, is usually celebrated in November with boat racing and festivities, especially in Phnom Penh when conditions allow. Exact dates and local programmes should be confirmed for the travel year.

Festivals offer meaningful cultural experiences but affect transport, accommodation and opening schedules. Dress respectfully at pagodas, follow local guidance and ask before photographing worship or private family observances. Our Cambodia events calendar lists API-managed events and can help connect a trip with public celebrations, exhibitions and performances.

Best timing by travel style

First-time visitors wanting predictable weather often prefer late November through February. Photographers may love the green season for reflective temple pools, active skies and saturated landscapes. Budget travellers can find value from May through October if they tolerate humidity and occasional disruption. Families with school-holiday constraints should build slower days around April heat or summer rain rather than avoiding Cambodia entirely.

Wildlife and nature timing depends on the exact activity. Waterfalls, forests and bird habitats change through the year, and ethical wildlife operators may adjust programmes for animal welfare or road access. Ask providers about current conditions instead of relying on generic seasonal promises.

What to pack in every season

Bring breathable clothing, a hat, high-SPF sunscreen, insect repellent and shoes suitable for uneven temple steps. A light layer helps in air-conditioned buses and cooler highlands. In wet months, add a rain shell, waterproof pouch and quick-drying sandals. Modest clothing that covers shoulders and knees is essential for many religious sites, regardless of temperature.

Build flexibility into the itinerary

A balanced Cambodia trip alternates demanding outdoor days with markets, museums, food experiences and unhurried evenings. Avoid scheduling every sunrise and transfer back to back. Select a route from our suggested itineraries, then adapt it to daylight, heat and local events. Cambodia is rewarding year-round when expectations match the season and the schedule leaves room for the country’s natural rhythm.

March to May is reliably clear but very hot, often above 35°C. Plan outdoor sightseeing for early morning and rest during the hottest part of the day. From June to October, short heavy downpours bring lush landscapes, fuller waterfalls, fewer visitors and lower prices.

Cambodia’s festival calendar is another reason to plan carefully. Khmer New Year takes place in mid-April, Pchum Ben falls in September or October, and the Water Festival usually brings boat races and celebrations in November.
