Cambodia Weather in March

Average Temperatures in March

Cambodia, located in Southeast Asia, experiences a tropical climate with distinct wet and dry seasons. March falls within the dry season, which typically lasts from November to April. This makes it a great time for tourists to visit, as the temperatures are warm but manageable, and there is little to no rainfall. However, the temperature can vary depending on the region, with the lowlands experiencing higher humidity and heat.

Overall Climate

In March, Cambodia experiences hot weather with daytime temperatures ranging between 30°C to 35°C (86°F to 95°F). The evenings are relatively cooler, with temperatures typically ranging from 22°C to 25°C (72°F to 77°F). Humidity levels are high, but the heat is more tolerable due to the dry conditions. It’s a sunny and dry month in most parts of Cambodia, especially in the lowland areas and cities such as Phnom Penh and Siem Reap.

Phnom Penh and Lowland Areas

In Phnom Penh, the capital of Cambodia, March temperatures are typical of the dry season. Daytime highs average 33°C to 35°C (91°F to 95°F), while nighttime lows can drop to 23°C to 25°C (73°F to 77°F). These warm temperatures make it an ideal time to explore the city, visit temples, and enjoy the riverside, as rain is rare in March. The lack of rain, however, means the city can be quite hot during the day, especially in the midday sun.

Siem Reap and Angkor Wat

In Siem Reap, the city closest to the famous Angkor Wat temple complex, March temperatures are slightly cooler than Phnom Penh due to the more rural environment. Daytime highs in Siem Reap range from 32°C to 34°C (90°F to 93°F), with nighttime lows around 22°C to 24°C (72°F to 75°F). This region is also experiencing dry conditions in March, which is perfect for visiting the ancient ruins of Angkor. As the temperature can still get hot during the day, it’s important to stay hydrated and protect yourself from the sun.

Coastal Areas (Sihanoukville, Koh Rong)

Cambodia’s coastal areas, including Sihanoukville and the nearby islands like Koh Rong, experience a slightly more moderate climate compared to the inland areas. The temperatures during the day are usually around 28°C to 32°C (82°F to 89°F), while the nighttime lows hover around 23°C to 25°C (73°F to 77°F). These coastal areas are typically more comfortable for beach-goers, as the sea breeze helps keep the air cooler and more breathable. However, the humidity can still be quite high in March.

Inland and Northern Areas (Ratanakiri, Mondulkiri)

In the northern and inland regions, like Ratanakiri and Mondulkiri, the temperatures in March are milder, particularly in the highlands. During the day, temperatures range from 25°C to 30°C (77°F to 86°F), while nighttime temperatures can drop to 18°C to 20°C (64°F to 68°F), making these areas more comfortable for outdoor activities. However, despite the cooler nights, daytime heat can still be intense. These areas also tend to experience lower humidity compared to the lowlands, which can make the climate feel more pleasant.

Precipitation Levels in March

Since March falls within Cambodia’s dry season, rainfall is generally very limited. The country experiences its highest levels of precipitation between May and October, but in March, the chances of rain are minimal. However, the dry season does not mean that the weather is completely free of any precipitation.

Phnom Penh and Lowland Areas

In Phnom Penh and the lowland areas, March sees very little rainfall, with average precipitation levels typically below 10mm for the entire month. Rainfall, when it does occur, is usually in the form of light showers or brief thunderstorms, though these are rare in March. The dry conditions help make the month of March a great time for exploring Cambodia’s cities, temples, and landscapes.

Siem Reap and Angkor Wat

Similar to Phnom Penh, Siem Reap experiences low rainfall in March, with average precipitation levels of 5mm to 10mm. The month is characterized by mostly dry weather, with clear skies and plenty of sunshine. Visitors to Siem Reap can expect very little rain, making it an ideal time to visit Angkor Wat and the other temples in the region.

Coastal Areas (Sihanoukville, Koh Rong)

On the coast, including Sihanoukville and the islands, March remains very dry, with average rainfall typically below 5mm. The months of March and April are usually considered the best times to visit Cambodia’s coastal regions due to the warm temperatures and the clear, calm seas. Occasional light rain showers are possible but do not significantly impact travel plans.

Inland and Northern Areas (Ratanakiri, Mondulkiri)

The northern and inland areas like Ratanakiri and Mondulkiri also experience very little rainfall in March. Average precipitation levels in these regions are generally under 10mm, and while the chance of rain increases toward the end of the month, March remains relatively dry. The cooler temperatures and lower humidity make this an excellent time for hiking, trekking, and visiting natural attractions like waterfalls and wildlife reserves.

Wind Patterns in March

Cambodia’s wind patterns in March are influenced by the seasonal transition between the northeast monsoon (dry season) and the onset of the southwest monsoon (rainy season). As the country is located in a tropical zone, winds tend to be relatively mild but can still provide some relief from the heat.

Phnom Penh and Lowland Areas

In the lowland areas such as Phnom Penh, the winds in March are generally light to moderate, with average wind speeds ranging from 10 km/h to 20 km/h (6 mph to 12 mph). Winds are often from the north or northeast and help to alleviate some of the daytime heat. The light breeze, especially in the evening, makes walking around the city more pleasant.

Siem Reap and Angkor Wat

In Siem Reap, wind speeds are similar to those in Phnom Penh, with light winds ranging from 5 km/h to 15 km/h (3 mph to 9 mph). The gentle breeze coming from the north helps cool the area, though it is not a strong wind. Winds are generally mild enough not to disrupt activities such as temple exploration or boating on the Tonle Sap Lake.

Coastal Areas (Sihanoukville, Koh Rong)

The coastal areas of Cambodia, including Sihanoukville and Koh Rong, experience more consistent winds in March due to the proximity to the ocean. Average wind speeds range from 15 km/h to 25 km/h (9 mph to 16 mph), with sea breezes providing a cooling effect. The winds are generally pleasant for beachgoers and water sports enthusiasts, although they are not typically strong enough to cause disruptions.

Inland and Northern Areas (Ratanakiri, Mondulkiri)

In the inland and northern regions, the wind speeds are generally mild, ranging from 5 km/h to 15 km/h (3 mph to 9 mph). These areas are shielded from strong winds by mountains and forests, creating a calm and peaceful environment for outdoor activities like trekking, wildlife watching, and camping.

Atmospheric Pressure in March

Atmospheric pressure in Cambodia remains relatively stable in March, with slight fluctuations in response to changing weather systems. As Cambodia is near the equator, the pressure remains within a typical range for tropical climates, generally around 1010 hPa to 1015 hPa. The stable pressure in March contributes to the relatively dry and clear conditions, although there can be occasional low-pressure systems that bring light rain or thunderstorms.
