Live Rain Radar for Nakhon Ratchasima
Track rain across Nakhon Ratchasima in real time with Rain Viewer, a hyperlocal rain radar app, updated every 5 minutes, street by street.
Local Weather Context
Rain in Nakhon Ratchasima — Korat — comes in short, intense bursts across the Khorat Plateau during the growing season. The city sits at 180–200m elevation on the plateau edge, which shapes how storms arrive: cells that build in the hills to the south and west can reach the city quickly, while northeastern parts of the province receive rain at different times from the same system. On a September afternoon, it can be raining heavily in the city centre while the eastern districts are dry.
Highway 2 — Mittraphap Road, the main artery between Bangkok and the northeast — cuts through the province and is subject to flash flooding where it crosses low-lying sections near the Mun River tributaries. For the enormous volume of freight and passenger traffic using this road, knowing which sections are in the rain band avoids both risk and delay.
Rain Viewer shows you exactly which part of Korat is in the rain right now — not a province-wide forecast, but block-by-block radar precision updated every 5 minutes.
Seasons
Wet season (May–October)
The southwest monsoon brings rain from late May, building through July and peaking in August–September. Rainfall is strongly afternoon-weighted. September is the peak risk month for flash flooding in the city centre.
Transition months (May and October)
May and October storms are the hardest to predict. Real-time radar is more useful than any extended forecast in these months.
Dry season (November–April)
Monthly rainfall falls below 30mm from December through March. Isolated convective showers can still develop in April.
NEW! Tap Anywhere to Inspect
2 Feb 2026One touch, and the rain at that exact spot explains itself—revealing intensity, precipitation type, cloud and air temperatures, and live national alerts, while making even the tiniest rain pockets easy to pinpoint and compare.
Use Cases
Timing freight departures on Highway 2
Korat is the gateway to the northeast for road freight from Bangkok. Rain on Highway 2's Pak Chong section creates serious risk for heavy vehicles. Real-time radar tells dispatchers whether a convoy should hold or move.
Planning jasmine rice harvest windows
Farmers time cutting windows around the tail of the wet season — seeing whether afternoon cells will track over the fields determines whether to commit a crew today or tomorrow.
Navigating the Korat city centre during peak afternoon storms
The city centre floods during heavy September events. Seeing a high-intensity cell approaching gives drivers and motorcyclists 20–30 minutes to reroute before streets become impassable.
Planning excursions to Khao Yai National Park
Khao Yai receives heavier rain than the city below. The park roads close during heavy rain. Checking the radar before driving Route 2090 into the park avoids arriving at a closed gate.
Coverage
Rain Viewer combines signals from northeast Thailand radar stations for Nakhon Ratchasima. From here, the same map shows rain developing in Chaiyaphum, Buri Ram, and Saraburi — useful if you're driving Highway 2 or managing operations across the plateau.

FAQ
How often does the Rain Viewer map update for Nakhon Ratchasima?
Every 5 minutes. During afternoon storm development — when Korat's rainfall risk is highest — this frequency captures conditions as they change.
Why does rain seem to hit one part of Korat but not another?
The Khorat Plateau's slight elevation variations and the influence of surrounding mountain ranges mean storm cells can be channelled in ways a regional forecast misses.
Can I set a rain alert for a specific location in Nakhon Ratchasima?
Yes. Set any location — a farm, a factory, a school — and receive a push notification when rain is approaching.
See the storm forming before it floods your route
Korat's rain is localised, plateau-shaped, and impossible to call from a weekly forecast. The map updates every 5 minutes — often 2–5 minutes faster than other apps — so by the time a cell is building over the hills to the southwest, you've already seen it heading toward the city.
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 storm clears Mittraphap Road and the convoy can move safely
- Rain alerts that trigger before rain arrives — set your farm, factory, freight depot, or school pickup point 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 into the city centre or pushing northeast toward Buri Ram
- 48 hours of radar history — see how yesterday's September storm moved across the plateau and recognise the same pattern forming this afternoon
- Multiple locations — track rain at your Highway 2 departure point, the Korat city centre, and your fields in the eastern districts at the same time
A 7-day forecast tells you September will be stormy. Rain Viewer tells you whether to release the convoy now or hold for 40 minutes.
