Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + Rice paddies outside Siem Reap are emerald green and flooded. Good for those well-known reflection shots of palm trees and water buffalo. Grab the shot early. Light shifts fast.
- + Hotel rates drop 30-40% from peak season. in Siem Reap where you can score heritage properties that were booked solid in December. Lock in the deal. Haggle anyway.
- + Mango season peaks in May. The Keo Romeat variety at Phnom Penh's Central Market tastes like honey with a hint of pine. Eat it messy. Juice runs everywhere.
- + Angkor Wat sunrise tours have half the crowds of high season. You'll share the reflecting pond with maybe 30 people instead of 300. Worth the alarm. Bring coffee.
Considerations
- − The heat is relentless by 10am. Stone temples radiate heat like pizza ovens, making afternoon temple runs miserable without proper planning. Plan shade breaks. Hydrate often.
- − Afternoon storms roll in around 3pm and can dump an inch of rain in 30 minutes, turning dirt paths around temples into red clay mud. Pack sandals. Embrace the mess.
- − The humidity hits 70% and stays there. Cotton shirts never fully dry between shower and temple visit. Switch to linen. Accept the wilt.
Best Activities in May
Top things to do during your visit
Angkor Temple Sunrise Photography Tours
May's cloud formations create dramatic sunrise backdrops at Angkor Wat. The monsoon buildup means streaky pink and orange skies you won't get in dry season. Temperatures sit at a manageable 78°F (26°C) at 5am, and low season means you'll fight fewer selfie sticks for that reflection shot. Arrive before 5. Stay patient.
Booking Tip: Book 2-3 days ahead through licensed operators who know which reflecting pools still hold water after morning irrigation. Some dry up by late May. Ask specifically for sunrise at Srah Srang instead of the main pond when crowds spike. Flexibility pays.
Mekong River Dolphin Watching from Kratie
The river levels rise in May, bringing Irrawaddy dolphins closer to Kratie town and making sightings more reliable. Morning boat trips run before the heat becomes punishing, and the swollen river means less boat traffic disturbing the pod of 80 remaining dolphins. Go early. Stay quiet.
Booking Tip: Arrange through guesthouses in Kratie rather than day-tripping from Phnom Penh. The 4-hour drive each way isn't worth it. Morning trips at 6am beat both heat and tour bus crowds. Sleep in town. Wake with the river.
Phnom Penh Street Food Night Tours
May evenings cool to 82°F (28°C) with breezes off the Tonle Sap. Good for navigating the grilled banana leaf parcels and num banh chok stalls along the riverside. The pre-monsoon humidity makes cold beer taste better, and mango sticky rice vendors appear on every corner. Follow the smoke. Eat standing.
Booking Tip: Join small-group tours that start at 6pm and finish by 9pm. Before the late-night rain hits. Look for guides who speak Khmer and can explain the difference between Khmer and Vietnamese noodle variations. Ask questions. Taste both.
Kampot Pepper Farm Visits
May marks the end of pepper harvest. Farms still have fresh green peppercorns on the vine that you won't taste any other time. The coastal breeze from Kep keeps temperatures 5°F cooler than inland, and afternoon storms rarely hit this side of the Elephant Mountains. Chew a pepper. Feel the burn.
Booking Tip: Visit in the morning when farm workers are harvesting. Afternoon heat drives everyone indoors. Multi-farm tours that include salt fields and durian orchards give you the full agricultural picture. Wear a hat. Bring cash.
Battambang Bamboo Train Rides
The pre-monsoon season means dry, firm ground along the tracks. The bamboo platform (norry) rides smoother and faster than during muddy September. Morning runs at 7am beat both the heat and tour groups from Siem Reap who arrive after 9am. Hold tight. Smile wide.
Booking Tip: The original track outside Battambang town closed in 2024. New track runs 4km (2.5 miles) further out. Tuk-tuk drivers know the new location but confirm before setting off. Leave early. Roads bounce.

May Events & Festivals
What's happening during your visit
Early May (date set by lunar calendar)
Royal Ploughing Ceremony
Cambodia's royal astrologers predict the coming harvest using sacred oxen in front of the National Museum. It's the only time you'll see the King in full traditional regalia outside the palace. Locals crowd the square for luck-based rice predictions and free traditional sweets. Arrive early. Stand back.
Early May (full moon)
Visak Bochea
Buddha's birthday turns every pagoda into a candle-lit wonderland. Locals carry lotus flowers and incense in processions around temples. Wat Phnom in Phnom Penh hosts the largest gathering, with monks chanting until midnight and street vendors selling banana-leaf wrapped desserts. Remove shoes. Respect silence.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The secret to beating temple heat: enter Angkor Thom through the south gate at 7am when it's still cool, save Angkor Wat itself for 5pm when the sun drops behind the library buildings and illuminates the bas-reliefs in golden light. Timing wins. Heat loses.
Local tuk-tuk drivers eat lunch at 11am for a reason. By noon the stone at Preah Khan becomes hot enough to burn bare feet through sandals. Follow their lead. Eat early.
May is when durian vendors appear on Highway 6 between Siem Reap and Battambang. The Monthong variety costs half Bangkok prices and tastes like custard mixed with garlic. Stop the car. Hold your nose.
The riverside night market in Phnom Penh moves indoors to the old railway station when storms hit. Same food, zero tourists, happens around 8pm. Follow the locals. Eat undercover.
Avoid These Mistakes
Trying to cram five temples before lunch. The heat index hits 100°F (38°C) by 11am and stone temples become ovens. Two temples before 10am, lunch and rest, two temples after 4pm. Pace yourself. Live to tell.
Wearing flip-flops on temple visits. May storms turn moss-covered stones at Baphuon and Ta Prohm into slip-and-slide hazards. Lace up. Save the flop for later.
Booking afternoon boat trips on Tonle Sap. The lake becomes choppy with pre-monsoon winds and you'll spend more time fighting waves than seeing floating villages. Book morning. Stay dry.
