Is March Right for You?
Weigh the advantages and considerations before booking
- + March lands at the tail of the dry season: cobalt skies still rule, river levels stay high enough for sunset boat trips, and sunrise over the Tonle Sap clocks in at 6:02 AM instead of February's 5:30 AM, good for photographers who refuse 4:30 AM alarms.
- + Hotel rates have just dropped 25-30% after Chinese New Year. Yet the weather hasn't turned brutal. You still face the same 94°F (34°C) afternoons as April, minus the humidity that turns temple walks into soup-swimming.
- + Mekong River dolphin watching tours from Kratie run daily in March before water levels drop too low. The 3-hour drive north from Phnompenh is pleasant now, no flooding, minimal dust, and roadside mango stands sell the first Nam Dok Mai of the season.
- + Street food vendors haven't switched to hot-season menus yet, so nom krok (coconut-rice cakes) still sizzle on cast-iron pans along Street 178, instead of the lighter, less satisfying rice porridge that dominates April-May.
- − UV index hits 8 by 10 AM, without serious sun protection, you'll burn in 15 minutes. The sun feels closer here, more intense, and shade is scarce around the Royal Palace complex where you're walking on white marble that reflects heat back up at you.
- − Afternoon thunderstorms start creeping in mid-month. These aren't the gentle drizzles of rainy season, they're violent 20-minute bursts that turn streets into rivers and send tuk-tuk drivers scrambling for cover, usually between 3-5 PM when you're trying to get back to your hotel.
- − March marks the start of hot season proper, which means every temple visit becomes a test of endurance. By 11 AM at Angkor Wat (the day trip everyone adds), stone courtyards radiate heat like pizza ovens and even Cambodian guides start suggesting shorter circuits.
Best Activities in March
Top things to do during your visit
March evenings deliver the year's most reliable sunsets, golden light reflecting off the Tonle Bassac for a full 45 minutes before the sky turns lavender. The river runs clean (ish) after dry season, so you can see the confluence where the Mekong and Tonle Sap collide. Boats leave from Sisowath Quay between 4:30-5 PM, returning after dark when the riverside promenade lights up with hundreds of food stalls grilling squid and pork skewers.
March mornings are good for market exploration, cool enough at 7 AM to handle the steam from bubbling vats of kuy teav (noodle soup) without melting. The Russian Market's food section hits different in March when vendors aren't yet wilting from afternoon heat, so you can watch your num pang being assembled on crusty baguettes that haven't turned soggy from humidity. Look for the woman who's been making num kroch (Khmer doughnuts) in the same corner stall since 1989, she fries them in palm oil that smells like coconut and caramel.
March's dry mornings make cycling between these two sites pleasant instead of the sweat-fest it becomes later in spring. The 15 km (9.3 mile) route takes you through neighborhoods most tourists never see, past the French colonial villas near Independence Monument, through the garment district where workers stream out at 5:30 PM shift change, ending at the killing fields where the grass has just started turning from brown to green. Start at 7 AM to avoid both traffic and heat; you'll reach Choeung Ek by 9 AM when the light is soft and the site's birds are singing.
March river crossings are smooth, the Mekong runs high enough for ferries to run every 20 minutes. But low enough that the 10-minute ride doesn't feel like white-water rafting. The silk weavers work outdoors in March, so you can watch the entire process from boiling cocoons to threading looms without getting rained on. The island's dirt roads are solid, not muddy, making it good for the 5 km (3.1 mile) loop past wooden houses on stilts where grandmothers wave from porches and kids splash in the shallows.
The 412 steps to this 11th-century hilltop temple are doable in March when humidity hasn't reached summer levels. At 8 AM, the laterite stone is still cool underfoot and the surrounding rice paddies glow electric green against red earth. The temple sits 130 m (427 ft) above the plain, on clear March mornings you can see all the way to the Cardamom Mountains. Monks chant at dawn and sunset. Time your visit to catch the 6:30 AM service when incense smoke mingles with river mist below.

March Events & Festivals
What's happening during your visit
While the actual New Year falls in April, March sees the city transform as locals stock up on traditional foods and decorations. The Central Market's flower section explodes with yellow and white jasmine garlands, and every corner has pop-up stalls selling krama scarves and traditional drums. It's the best time to see pre-festival Phnompenh before it empties out for the holidays.
While the main festival happens in November, March is when racing boats are hauled onto the riverbanks for repairs. You can watch barefoot craftsmen sanding dragon boat prows while old men play chess nearby, it's like stepping behind the curtain of Cambodia's biggest celebration, minus the shoulder-to-shoulder crowds.
