Monitor rain across Chon Buri, Pattaya, and the Eastern Seaboard in real time. Updated every 5 minutes.
Chon Buri province stretches along Thailand's Eastern Seaboard, encompassing the resort city of Pattaya, the industrial zone of Laem Chabang, and Si Racha's coastal communities. Sea breezes interact with inland convection to create localised storm patterns that can differ dramatically between the coast and areas just 20 km inland.
Onshore winds bring frequent afternoon and evening storms. Rainfall is heaviest in September–October, often exceeding 250 mm per month. Pattaya's beachfront can see sudden squalls that develop over the Gulf of Thailand.
November brings the northeast monsoon onset with occasional coastal storms. April sees rising humidity and scattered pre-monsoon thunderstorms.
Cool northeast winds keep skies mostly clear. Pattaya and coastal areas enjoy steady weather ideal for tourism, with rainfall typically below 40 mm per month.

One tap, and the rain at that precise spot tells its own story—showing intensity, precipitation type, cloud and air temperatures, and live national alerts, while making even the smallest rain pockets easy to identify and compare.
Pattaya's outdoor activities — island boats, beach events, water sports — depend on accurate short-term weather tracking. Radar helps tour operators decide whether to launch boats or reschedule excursions.
Laem Chabang, Thailand's busiest deep-sea port, needs radar monitoring for crane operations and container handling that must pause during thunderstorms.
The Eastern Seaboard Industrial Estate and surrounding factories monitor radar to protect outdoor operations and workforce safety during sudden storms.
RainViewer provides full radar coverage across Chon Buri province, extending over the Gulf of Thailand coastline and inland to Chachoengsao. Offshore radar data helps track storms forming over the gulf before they make landfall at Pattaya or Bang Saen.
“A little overenthusiastic at times with rain predictions, but it's accurate and spot on for radar images, and it's the one radar app I've kept and not uninstalled”

I must update my feedback once again – this is still the best brain app in the app store. The issue I was experiencing was with my phone, not this top-tier app. One feature I particularly like is the widgets.

Yes. Radar coverage extends well offshore, so you can see rain cells forming over the gulf and track their movement towards the coast.
Very accurate. Sea breeze convergence storms show clearly on radar 15–30 minutes before reaching the beach, giving time to seek shelter.
Radar covers the waters around Koh Larn and Koh Sichang. Whilst island-specific detail is limited, you can see storm cells approaching the islands clearly.
Whether you're on Pattaya Beach or managing operations at Laem Chabang, stay ahead of the weather.
