Cambodia weather in March is marked by rising heat and increasing chances of short but intense rainstorms. Expect daytime temperatures generally in the low- to mid-30s Celsius, cooler nights, and a mix of long sunny stretches interrupted by sporadic downpours.
What the climate looks like in March
March sits between the cooler dry season and the full southwest monsoon. Climatic summaries for the month report an average temperature around 33C with nighttime lows near 21.9C, producing an overall daily swing of roughly 9C. Toward the end of the month temperatures often climb further and occasional readings approach the high 30s or low 40sC in exposed areas.
Humidity tends to rise as the month progresses. Some reports show relative humidity figures moving into the mid-to-high 70s percent across much of the country. Rainfall in March is typically light compared with the wet season, yet sudden storms and thunder can occur. On average there are only a few rainy days during the month, but rainfall events are sometimes heavy and accompanied by strong winds.
Key weather features and what to expect
Days in March often start with bright sun that can last for several hours, making mornings and early afternoons ideal for temple visits and outdoor activities. Later in the day brief, powerful showers or thunderstorms are common, especially after prolonged heat. These storms can bring lightning, fierce gusts and, in rare cases, hail.
Because the pattern combines extended dry spells with episodic violent rainfall, tourism flows often concentrate in the mornings with fewer visitors on site in the afternoons. Many travellers find this split-day rhythm helps them plan sightseeing around the forecasted storm windows.
- Typical daytime highs: low to mid-30s C
- Typical nighttime lows: around 22C
- Rain: a few heavy, short-lived storms rather than prolonged rain
- Humidity: rising through the month, often into the 70s %
Practical travel tips for March visitors
Monitor short-term weather forecasts and plan outdoor activities for the morning when possible. Because storms can develop quickly after long sunny spells, build flexibility into each day and allow extra time for transfers and travel.
Pack for heat with lightweight, breathable clothing and include sun protection: a wide-brimmed hat, sunglasses and sunscreen. Also have compact rain protection such as a lightweight waterproof jacket and a small umbrella for sudden showers.
- Carry water and plan rest breaks — daytime heat can be intense.
- Store critical documents and electronics in waterproof pouches during storm-prone periods.
- Use a portable fan or a folding hand fan for on-the-go cooling.
- Book morning tours for open-air sites to avoid afternoon downpours.
Cultural context: festivals and seasonal activities
March often overlaps with important Buddhist observances in Cambodia, including the full-moon related ceremonies held by many communities. These events typically involve temple visits and candlelit processions, and timing shifts with the lunar calendar; visitors should check local festival calendars when planning a trip.
The month also coincides with local fruit harvests in some provinces, so markets can offer a wide range of fresh, seasonal produce. Floating markets and riverine communities may be lively in the cooler parts of the day, but traders and boat operators may pause activity during late-afternoon storms.
Who should consider traveling in March?
March suits travellers who prioritise dry, sunny mornings and dont mind short-duration weather interruptions later in the day. It can be a good choice for beachgoers and temple visitors who structure outings around the cooler hours.
Families and cost-conscious travellers may appreciate lower shoulder-season rates and easier access to accommodation and attractions. However, anyone sensitive to heat or seeking consistently dry weather might prefer the earlier dry-season months when humidity and temperatures are generally lower.
For travellers planning overland connections through the region, practical transport guides can be useful; for example, detailed guidance on cross-border options and timings is available for the Ho Chi Minh City to Phnom Penh transport options.
Comparisons and alternatives
Compared with the peak wet season (roughly JuneOctober in much of Cambodia), March offers fewer days of sustained rain but a higher likelihood of brief, intense storms. Relative to the cool, dry months of December to February, March is noticeably warmer and more humid as the country transitions toward the monsoon.
If you want to avoid afternoon storms altogether, consider travelling earlier in the dry season. For travellers who don't mind rain and are seeking greener landscapes and lower prices, the rainy months provide a different experience; there is a dedicated guide with practical advice on travelling during wetter months in Cambodia in our rainy season tips.
