Live rain radar for Saraburi, updated every 5 min. See cells over the Pasak floodplain before they flood Highway 1 or Highway 2 at the junction. Free.
Saraburi sits at the gateway to both the north and the northeast of Thailand — Highway 1 and Highway 2 diverge here, making it one of the most traffic-dense transit corridors in the country. Rain that falls in Saraburi affects not just local residents but hundreds of thousands of vehicles in transit daily. A cell stalling over the Pasak River floodplain can flood the highway sections that heavy freight relies on, creating multi-hour delays that ripple through the supply chain.
The Pasak River has a well-documented history of flooding in years when the monsoon delivers above-average rainfall. Upstream flooding in Saraburi can precede reservoir intervention by hours, making real-time radar more valuable than any forecast.
RainViewer combines central Thailand radar for Saraburi. From here, you can track rain in Lopburi, Nakhon Ratchasima, and Nakhon Nayok — useful if you're driving Highway 1 or Highway 2 or monitoring upstream conditions in the Pasak catchment.
Afternoon and evening storms from late May through October. Highway flooding events are documented particularly on sections between Sara Buri town and Kaeng Khoi.
Real-time radar more useful than forecasts.
The industrial corridor runs at full capacity.
Rain on the highway here creates real transit delays. Dispatchers at Bangkok logistics hubs check the radar on the Highway 1–2 corridor at Saraburi before releasing convoys.
Plant safety managers at the Kaeng Khoi cement and industrial operations use radar to issue weather holds before cells arrive.
A cell sitting over the Pasak River bridge section can back up traffic for hours — seeing it on the radar before departure changes route decisions.
Every 5 minutes. During peak monsoon season when the highway corridor experiences its highest flood risk, near-real-time radar is the most actionable information available.
Yes. The radar shows which road sections are in a rain band in real time — not just whether it's raining in the province, but exactly where.
