Practically speaking, Cambodia has four seasons: 1) November-February, cool/dry; 2) March-May, hot/dry, 3) June-August, hot/wet; 4) September-October, cool/wet. The hottest days of the hot season rarely climb above 35°C though the sun can be quite intense. The cool season may push the mercury as low as 20°C. The monsoons between June and October follow a regular pattern, clear mornings with 1-3 hour rains in the afternoon. The cool dry season is more comfortable but the regularity of the wet season rains make them easy to plan around.
