Is May Right for You?
Weigh the advantages and considerations before booking
- + The first rains paint the Angkor paddies a luminous green, a color that only exists for a few weeks. Grab your camera: the moats at Bayon and Angkor Thom turn to glass, flipping the stone towers upside-down in flawless mirror images you simply will not catch in dry-season months.
- + Shoulder-season bargains kick in as occupancy slides: hotel rates drop 30-40% from the peak. Even five-star properties in Siem Reap start unlocking rooms at these prices about two weeks before you show up, no haggling required.
- + May is mango month. Street carts on Pub Street wheel out crates of kev mangoes, iced and dusted with chili salt, served for breakfast. One bite of the sweet-sour flesh slices through the morning humidity faster than any cup of coffee can manage.
- + After 2pm the tour buses evaporate. Storm clouds herd them back to town, leaving Ta Prohm's strangler-fig corridors quiet. Stick around: the pre-rain light turns gold, and you'll have the trees, the stones, and the shadows to yourself.
- − By 11am the heat index is already flirting with 40°C (104°F). Attempting a full temple circuit without constant water stops and a shady lunch break edges from foolish to dangerous. The nearest clinic is half an hour away.
- − Afternoon thunder rolls in, snaps power lines, and rural guesthouses between Siem Reap and Battambay go dark for 2-4 hours. No electricity means no electric pumps, so bucket showers become the evening routine.
- − Dust becomes mud on the laterite lanes around Angkor. A tuk-tuk ride from Angkor Wat out to Banteay Srei morphs from a breezy 45-minute cruise into a splattered, wheel-spinning hour-long slog.
Best Activities in May
Top things to do during your visit
Set your alarm for 5am. The air stays below 25°C until 7:30am, good for pedaling the 17km (10.6 mile) Angkor Grand Circuit. May's low sun strikes the bas-reliefs at a 65-degree angle, carving shadows you will never see in December. By 6am the lotus flowers in the moats are wide open, and dragonflies stencil moving silhouettes across the stone.
Tonle Sap climbs 3-4 meters (10-13 feet) in May, submerging the mangrove roots around Kampong Phluk. Kayak through the flooded forest where water laps at the second-floor balconies of stilt houses. Mekong dolphins slip in from the main river for the morning feed, and the lake is still clear enough to spot them underwater, visibility you will not get once June stirs up the silt.
At Phsar Chaa market in Siem Reap, May delivers fresh turmeric knobs, crisp green papaya, and morning glory that vanish once July's heavier rains arrive. Cooking classes kick off at 8am while the stalls are in full swing and the air is still bearable. You'll pound fish amok using snakehead netted the previous night from Tonle Sap and coconut milk pressed from nuts at their sweetest, just before the monsoon.
May's stacked clouds ignite the Mekong sunset palette: rose, copper, violet. The river is high enough for bigger boats yet still clear of June's brown increase. At 5pm the mercury slips to 28°C (82°F), river breezes kick in, and café terraces switch from iced coffee to cold beer service as the sun drops behind the Royal Palace.
This is the final month of gin-clear water before the monsoon stirs the sediment. Off Koh Rong Samloem's Saracen Bay you can still see 20 meters (65 feet) down. Day boats stop at Three Bear Beach to snorkel with parrotfish in the shallow coral, then drift to Long Beach where the sand squeaks like fresh snow. Captains know which coves stay flat when the afternoon breeze picks up.
May Events & Festivals
What's happening during your visit
In early May the royal oxen shuffle into Veal Preah Meru field and choose among trays of rice, corn, beans, sesame, grass, and water. The 13th-century ritual begins at 8am with a procession from the Royal Palace and music played on drums and oboes unchanged since Angkorian times.
For Buddha's birthday, temples glow with candle processions. At Wat Phnom, monks circle the stupa at 6pm while paper lanterns rise above the Mekong. Up in Siem Reap, Wat Preah Prom Rath keeps 300 monks chanting through the night. Their saffron robes flicker in torchlight against grey stone courtyards.
