🇰🇭Cambodia

Cambodia spans 10°25′–14°41′N, a Southeast Asian country covering approximately 181,035 km² on the Indochinese peninsula bordering Thailand, Laos, and Vietnam, with a 443 km coastline on the Gulf of Thailand; dominated by a low central plain around the Tonle Sap, the great seasonally-pulsing freshwater lake that doubles in size during the wet season as the Mekong reverses its flow into it, and the Mekong corridor, ringed by the Cardamom Mountains in the southwest with Phnom Aural at 1,810 m as the country's highest peak, the Dangrek escarpment along the Thai border in the north, and the Annamite foothills in the east. The climate is uniformly tropical—tropical savanna (Aw) across most of the country with a tropical monsoon (Am) tendency on the wet Cardamom slopes and the southwest coast.

Phnom Penh averages 26°C in January and 30°C in April with 1,400 mm rainfall almost entirely from the southwest monsoon May–October, with the severe pre-monsoon hot season April–May regularly above 38°C; Siem Reap near the Tonle Sap records similar temperatures; Sihanoukville on the southwest coast averages 27°C in January and 28°C in April with a staggering 3,440 mm, among Southeast Asia's wettest towns; Battambang inland records 26°C in January and 30°C in April with 1,250 mm; the Cardamom Mountains receive 4,000–5,000 mm annually. Major events include the severe 2011 Mekong floods, the worst in decades, displacing 1.7 million people and submerging Angkor Wat, the 2013 floods, recurrent severe Tonle Sap flow disruption from upstream Mekong damming combined with climate change shrinking the lake's wet-season reach, the intensifying 2015–16 and 2019–20 droughts, the April 2016 record of 42.6°C at Preah Vihear, and growing food-security pressure from Mekong delta sea-level rise and salinisation.
