Cambodia’s climate runs hot and humid year-round, with two main seasons: wet and dry. The dry season (November–April) is generally the most comfortable for sightseeing at Angkor Wat or exploring Phnom Penh, especially December–February when temperatures are lower and rainfall is minimal. The wet season (May–October) brings frequent showers, which can cool things down but also lead to flooding in some regions. Many travelers find June–August suitable if they don’t mind occasional rain, as the landscape turns lush green, and crowds can be lighter. If you’re sensitive to heat, avoid the peak of the hot season (March–May). On balance, visiting between December and February ensures manageable weather and prime conditions for touring temples and rural areas alike.
