Live Rain Radar for Khon Kaen
Track rain and storms across Khon Kaen and the central Isan plateau. Updated every 5 minutes.
Local Weather Context
Khon Kaen is the commercial and educational hub of central Isan, situated on the Khorat Plateau at about 170 m elevation. The Chi River runs through the province, and its flat terrain makes it susceptible to widespread flooding when heavy rains saturate the clay-heavy soil. As Isan's largest city, weather disruptions affect a population of over 400,000.
Seasons
Wet season (May–October)
The southwest monsoon brings 80% of annual rainfall. July–September are the wettest months, with averages of 200–270 mm. Afternoon convective storms are common, sometimes developing into severe thunderstorms with hail over the open plateau.
Transition months (November, April)
November brings cooling temperatures and the last rains. April is the hottest month — temperatures regularly exceed 38°C with occasional severe pre-monsoon thunderstorms.
Dry season (December–March)
Cool, dry conditions with less than 20 mm monthly rainfall. The Chi River drops to low levels, and water management becomes critical. January temperatures can fall below 10°C on clear nights.

Who Needs Rain Radar Here
University community
Khon Kaen University, Thailand's largest northeastern campus, has over 40,000 students. Most travel by motorbike, making real-time rain tracking essential for daily commutes.
Sugar cane farmers
Khon Kaen province is Thailand's largest sugar cane producer. Rain during harvest season (December–April) can damage cut cane and make field access impossible for trucks.
Silk weavers
Traditional mudmee silk production involves outdoor dyeing and drying processes that must be protected from unexpected rain.
Logistics operators
As Isan's transport hub, Khon Kaen's highways and railway connections need weather monitoring. Heavy rain disrupts the logistics chain feeding Bangkok's markets.
Radar Coverage
RainViewer provides excellent coverage across Khon Kaen and the surrounding plateau. The flat terrain means minimal radar obstruction — storm cells are visible from great distances. Coverage extends to Udon Thani in the north, Maha Sarakham to the east, and Chaiyaphum to the southwest.

FAQ
Why are Isan thunderstorms sometimes severe?
The flat, open plateau allows storm cells to develop and intensify without topographic interference. Combined with strong daytime heating, this produces occasionally severe storms with hail, strong winds, and heavy rain.
Can radar detect hail-producing storms?
Very intense radar echoes (shown in bright red or purple) often indicate hail. If you see these colors approaching on the radar, take shelter immediately.
How does radar help during sugar cane harvest?
Farmers and mill operators check radar to plan cutting and transport schedules. Rain-free windows of 6+ hours are needed for efficient harvesting and field truck access.
See rain in Khon Kaen before it reaches your field or your route
Khon Kaen's rain is plateau-fast, localised, and exactly the kind of storm a 7-day forecast misses entirely. The map updates every 5 minutes — often 2–5 minutes faster than other apps — so by the time a cell is building south of the city, you already know whether it's tracking toward your fields or the Highway 2 corridor.
Rain Viewer Essential gives you:
- A 2-hour rain forecast in 5-minute slices — not hourly blocks, so you can see the exact window when the afternoon storm clears and the harvest crew or convoy can move
- Rain alerts that trigger before rain arrives — set your farm in the eastern districts, the Kaen Nakhon lakeside, or your Highway 2 waypoint and get notified while you can still change your plans
- Direction arrows on the map — so even when the animation is unclear, you can see whether the cell is tracking north of the city toward Udon Thani or pushing south toward Maha Sarakham
- 48 hours of radar history — see how yesterday's plateau storm moved across the Phong River catchment and recognise the same pattern forming this afternoon
- Multiple locations — track rain at your cassava fields, the Khon Kaen hospital approach road, and your Bangkok-bound freight route at the same time
A 7-day forecast tells you August will be wet. Rain Viewer tells you whether to send the cutting crew in now or hold for two hours.
