Local climate notes
Battambang lies in the rain shadow of the Cardamom range, making it one of the driest provinces in Cambodia — which is also why it is the country's main rice-growing region and unusually dependent on the timing of the rains. The dry season runs December to April, with afternoon humidity sometimes dropping below 50%, a level rarely seen elsewhere in Cambodia.

This measures upstream rainfall, not river level. Official levels and discharge come from the Mekong River Commission (MRC). Upstream rainfall causes the level, and is visible several days earlier. MRC
Tonlé Sap
The Mekong now stands higher than the lake, so the Tonlé Sap river runs backwards and pumps water in. Fish move upstream into the lake to spawn. This is when the lake expands fastest.
Mekong basin rainfall: 39 mm over the past 72 hours, 30 mm forecast for the next 72.
This is a seasonal estimate combined with basin rainfall, not a measured level. Official water level and discharge come from the Mekong River Commission (MRC). The timing of the reversal varies year to year and has shifted noticeably over the past two decades.
