Track rain across Khon Kaen in real time with Rain Viewer, a hyperlocal rain radar app, updated every 5 minutes, street by street.
Khon Kaen rain comes in short, intense bursts across the Khorat Plateau during the growing season — exactly the kind of storm that a 7-day forecast misses and a live radar catches. The city is the commercial and medical hub of the upper northeast, drawing patients, students, and freight from a large surrounding region. An afternoon storm that floods the Kaen Nakhon lakeside road or the commercial area around Mittraphap Road affects tens of thousands of people who need that information in real time.
The province's agricultural land — cassava, sugarcane, kenaf, and rice — depends on precise monsoon timing. Fields in the eastern districts receive storms from a different angle than those near the Phong River, and the difference between a cell tracking north versus south of the city can determine whether a harvest window holds.
Daily afternoon storms, August and September the wettest. The Phong River rises through this period.
Forecast reliability drops; real-time radar most useful.
Monthly rainfall below 20mm from December through February.

Un seul geste, et la pluie à cet endroit précis se dévoile : intensité, type de précipitation, température des nuages et de l’air, alertes nationales en direct — même les plus petites poches de pluie deviennent faciles à repérer et à comparer.
Farm managers need to know if the afternoon cell will deliver harvest-disrupting rain or pass to the north. The radar makes this decision possible an hour in advance.
Families driving from Udon Thani, Kalasin, or Roi Et check the radar before committing to a journey — a heavy cell on Highway 2 creates real risk for non-urgent travel.
Rain on Highway 2 between Khon Kaen and Bangkok is a daily concern for long-haul operators. Real-time radar on the route tells dispatchers which cells to route around.
Rain Viewer combines northeast Thailand radar for Khon Kaen. From here, you can track rain in Udon Thani, Kalasin, and Maha Sarakham — useful if you're driving Highway 2 or managing operations across the Phong River catchment.
« Un peu trop enthousiaste parfois avec les prévisions de pluie, mais c'est précis et fiable pour les images radar, et c'est la seule appli radar que j'ai gardée sans la désinstaller »
Duncan Stewart
« Je dois encore modifier mon avis : c’est toujours la meilleure application météo de l’App Store. Le problème que je rencontrais venait de mon téléphone et non de cette application haut de gamme. Une fonctionnalité que j’apprécie particulièrement, ce sont les widgets. »

Every 5 minutes. During the afternoon convection window typical of the plateau, this captures the exact position of a cell as it moves.
Yes. Set any rural location and receive a notification when rain intensity crosses a threshold you define.
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 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.
