Rain in Ubon Ratchathani: What You Need to Know
Ubon Ratchathani sits at the eastern edge of the Khorat Plateau, where the Mun and Chi rivers converge before crossing into Cambodia. The province receives some of the highest rainfall in the northeast — approximately 1,400mm annually — and the river system means that flood risk accumulates through the season as upstream catchments drain eastward. The 2019 flooding of Ubon Ratchathani, which reached central streets and displaced thousands, brought national attention to the cumulative river risk here.
Ubon is also one of Thailand's most important jasmine rice producing provinces. Farmers in the eastern districts time their harvest to the final weeks of the monsoon — a critical window where knowing whether the rain has truly ended determines the whole season's outcome.

Why You Need a Rain Radar in Ubon Ratchathani
Timing jasmine rice harvest in the eastern districts
Harvest timing in October requires knowing whether the afternoon cell will reach the fields before the cutting crew finishes. Missing the window by a day costs the whole plot.
Monitoring the Mun River flood level during the wet season
Rain in Surin and Si Sa Ket reaches Ubon 12–24 hours later. The radar shows the upstream picture the local gauge can't.
Planning the Chong Mek border crossing to Laos
Sections of Highway 212 between Ubon and the border can flood during heavy monsoon events. Traders and travellers check the radar before long drives in September and October.
