Whats the worst time of year to visit Angkor?
For weather, it has to be April which can be unbearably hot (38C, 100F) and dry. The air is dusty and hazy, a lousy time for photography. For crowds that would be December and January, though these months do offer the coolest weather. Christmas/New Year week as well as Chinese New Year can be especially very very crowded times. Khmer New Year (April 14-16) brings half of Cambodia to the temples, but foreign tourists are few and far between. Khmer New Year is a very interesting cultural experience but given that the Angkor park is turned into one big party, it’s not the best time for exploring temples.
