When is the best time to visit Phnom Penh, Cambodia?

Seasonal Weather Patterns

Phnom Penh has a tropical climate divided into two primary seasons: the dry season and the rainy season.

Dry Season (November to April)

This is the most popular period for visitors. From November to February, the weather is mild and dry, making it ideal for walking through the Royal Palace or exploring the Central Market. From March to May, temperatures rise significantly, often becoming oppressive with high humidity and intense sunlight.

Rainy Season (May to October)

Expect frequent, heavy downpours, usually occurring in short bursts in the afternoon or evening. While the rain can cause localized flooding on city streets, it cools the air and turns the surrounding landscapes lush and green. Crowds are thinner, and the city feels less congested.

Choosing Your Travel Window

• Best for Sightseeing: November to February. The cooler temperatures allow for outdoor exploration without extreme heat exhaustion.
• Best for Budget/Quiet: June to September. Lower demand often leads to better availability of transport and accommodation.
• Months to Consider Avoiding: April is the hottest month of the year, which can make outdoor activities physically draining.

Key Events and Price Fluctuations

The Khmer New Year (mid-April) is a major national holiday. While culturally significant, many businesses and shops in the city center close as residents return to their home provinces. This period can see a surge in domestic travel, affecting local transport availability.

The Water Festival (November) attracts large crowds to the riverside. While vibrant, expect heavy traffic congestion and limited space near the Tonle Sap and Mekong rivers.

Packing and Preparation

Regardless of the season, visitors arriving via Techo International Airport (KTI) should prepare for high humidity.

• Dry Season: Lightweight, breathable cotton clothing, high-SPF sunscreen, and a wide-brimmed hat.
• Rainy Season: A sturdy umbrella, waterproof footwear, and a dry bag for electronics.
• General: Modest clothing that covers shoulders and knees is required for visiting pagodas and government buildings.
