November through March is the driest period, yet the very best time to visit Siem Reap runs from December to January. These months show reliably bright and sunny days—comfortable conditions for taking part in the Angkor Wat International Half Marathon. However, winter is also a popular season for a trip with skyrocketing prices, so book well in advance. Late spring can be oppressively hot and wet, with the level of humidity jumping even higher in May. But this is also when lotus blooms begin and mango season is in full swing. June marks the start of the wet season with frequent showers in the afternoon. But don't let the rain deter you—Kampong Phluk Floating Village and other famous attractions are less crowded, prices are keen, and lush landscapes look fantastic. Just pick up an umbrella and full steam ahead!
