Live rain radar for Pathum Thani, updated every 5 min. See storms on the Don Mueang–Rangsit corridor before they flood the airport access roads. Free.
Pathum Thani is embedded in living memory of the 2011 flood — the worst flooding of the Chao Phraya basin in five decades, which submerged large sections of the province for weeks. The hard lesson from that event is that Pathum Thani's flood risk is not just from local rain: it's from the entire catchment system that drains through it. Rain in Chiang Rai in September can reach Pathum Thani as rising river levels in October.
For everyday rain events, the province's flat terrain and dense urban development along the Don Mueang–Rangsit corridor floods quickly in heavy afternoon storms. Don Mueang Airport sits in this corridor — rain that sheets across the airport access roads affects arrivals and departures for thousands of passengers.
RainViewer combines central Thailand radar for Pathum Thani. From here, you can track rain in Bangkok, Nonthaburi, and Ayutthaya — useful if you're commuting on Vibhavadi Rangsit Highway or need to see upstream river conditions.
Daily afternoon storms, peak in August and September.
The highest-risk month for compound flooding — local rain plus high river levels from upstream catchments.
Minimal local rainfall.
Access roads to Don Mueang flood during heavy afternoon rain. Travellers need to know whether a cell will hit during their drive. A 30-minute radar window changes the departure decision.
Rain holds require advance notice — the radar provides it.
Local rain adds to an already-high system. Homeowners in canal-adjacent areas watch the radar to anticipate when local rain will compound existing high water levels.
Every 5 minutes. During the afternoon storm window and the critical October transition when local rain and river levels combine, near-real-time radar is the most actionable tool.
Yes. The radar covers the full Chao Phraya basin including Nakhon Sawan and Ayutthaya upstream.
