Is March Right for You?
Weigh the advantages and considerations before booking
Advantages
- + 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.
Considerations
- − 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
Phnom Penh in March is a city in transition. The dry season's peak heat has arrived, with afternoons that feel thick and still under a bright, unrelenting sun. You will feel the warmth radiating from the stone walkways of the Royal Palace complex and see the city's green spaces, like the park around the Independence Monument, begin to thirst for the rains that are still a month away. Locals move with a measured pace during the midday hours, seeking the shade of wide awnings and the respite of iced coffee. By evening, a slight coolness returns to the air, and the scent of charcoal smoke and grilling meats begins to drift from riverside stalls. This month sees a subtle shift in the rhythm of Phnom Penh. While the calendar shows no major festivals, the climate data reveals a telling change: March brings the first significant rainfall since December, averaging over an inch. These are not the prolonged downpours of summer but brief, intense showers that can sweep in unexpectedly, leaving the streets steaming and the air momentarily cleansed of dust. Carry a light umbrella. Enjoy the city's indoor spaces, its poignant museums, its airy palace halls, before the true wet season curtain falls. Navigating Phnom Penh in March requires an awareness of this variable weather. Mornings are often clear and hot, good for an early start to any tour. Afternoon plans should accommodate the possibility of a sudden, heavy rain, which can make for a dramatic view from a covered terrace along the Tonle Sap riverfront. The humidity remains constant, a blanket that makes the cool marble floors of the National Museum a welcome sensation underfoot. This is not a month of crowds or major events. But rather a window to experience the city's profound history and daily life with a certain clarity, under skies that can change from searing blue to stormy grey in a matter of minutes.
Phnom Penh: The Killing Fields & Tuol Sleng Genocide Museum
culturalA sobering journey into Cambodia's recent past. You will hear the haunting audio guide narratives amidst the quiet of the memorial stupa, see the fragmented cloth and bone still emerging from the earth after rains, and feel the heavy silence that hangs over the former schoolrooms of Tuol Sleng. This tour provides essential context, connecting the museum's stark portraits to the rural site where events culminated.
It is an indispensable, emotionally powerful engagement with the history that shapes modern Cambodia.
Insider tip: Visit Tuol Sleng first thing in the morning when it opens to experience its halls in relative quiet before the day's heat builds.
This month: The brief afternoon rains common in March can make the paths at the Killing Fields site muddy; sturdy, closed-toe shoes are advisable.
Phnom Penh: Silk Island Bike Tour / E-Bike or Tuk Tuk
adventureA refreshing escape from the city's traffic, taking you across the Tonle Sap by local ferry to the weaving villages of Koh Dach. You will hear the rhythmic clack of wooden looms from open workshops, smell the lush greenery of island paths, and feel the river breeze as you pedal past stilted houses and silkworm farms. Choosing an e-bike eases the journey in the March heat, while a tuk-tuk option provides a shaded alternative.
It delivers a tangible connection to a centuries-old craft and the tranquil, rural pace of life just minutes from downtown Phnom Penh.
Insider tip: Pause at a small family-owned workshop to feel the surprisingly soft texture of raw silk thread and see natural dyes simmering in clay pots.
This month: The March heat makes the early morning departure valuable, and the ferry crossing can be breezy and pleasant before midday.
Phnom Penh: Royal Palace, S21, Killing Fields & More Tour
culturalYou will see the dazzling floor tiles of solid silver within the pagoda, feel the cool of the throne hall's mirrored walls, and later confront the confronting exhibits that document a darker chapter. The curated travel between sites allows for necessary mental transition.
It creates a profound narrative arc, contrasting the pinnacle of Khmer monarchy with the depths of its 20th-century tragedy.
Insider tip: At the Royal Palace, look for the intricate mural depicting the Ramayana that wraps around the compound's wall, a masterpiece of detailed storytelling often passed by quickly.
This month: The marble and tile floors of the Royal Palace can become quite warm underfoot by late morning in March. Visiting these spaces early in the tour itinerary is more comfortable.

March Events & Festivals
What's happening during your visit
Late March
Cambodian New Year (Chaul Chnam Thmey) Preparations
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.
Throughout March
Mekong River Water Festival (Bon Om Touk) Remnants
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.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The riverside promenade between Street 104 and 130 has free public exercise classes at 6 AM, join the aerobics sessions where 200 locals dance to Khmer pop while the sun rises over the Mekong
March is when tuk-tuk drivers start their 'hot season pricing', agree on fares before getting in, and if someone quotes more than double the meter rate, just walk 20 meters to the next driver
The best coffee in Phnompenh isn't from cafes, it's from the woman who sets up her Vietnamese-style drip filters on Street 13 every morning at 6 AM. She uses condensed milk from Thailand and her ice comes from a block she hacks with a machete
Book accommodations with pools, March afternoons hit 94°F (34°C) and you'll want to dive in between sightseeing. Even budget guesthouses on Street 258 have started adding small rooftop pools
Avoid These Mistakes
Trying to visit Angkor Wat as a day trip from Phnompenh, March heat makes the 5-hour each way journey brutal, and you'll arrive at the worst time (11 AM) when stone surfaces burn
Wearing flip-flops for temple visits, March sun heats stone to foot-burning temperatures, and some temples require removal of footwear entirely (ever walked barefoot on 110°F (43°C) sandstone?)
Booking river cruises for noon departures, March storms typically hit at 3 PM, so morning cruises get perfect weather while afternoon ones get soaked
