Bang Phli Yai is a factory and airport-logistics district in Samut Prakan, southeast of Bangkok, where Suvarnabhumi Airport and the Bangna-Trad Highway shape the day. Rain here arrives as slow afternoon cells, and a Bang Phli Yai rain radar shows whether the next one reaches Kingkaew Road before a shift change. Hyperlocal radar shows where the rain is and where it is heading.
The district lies on the flat delta plain near the Gulf of Thailand, with canals and fish ponds around the industrial estates. Sea-breeze storms from the Gulf reach it from the south and combine with heat from the airport and factories to build cells. A standard forecast for Samut Prakan gives a total, not the timing.
RainViewer shows precipitation over Bang Phli Yai with data from the Thai Meteorological Department, the national weather service. The live rain map refreshes about every 5 minutes, so it shows whether a cell over Suvarnabhumi is moving towards the Bangna-Trad Highway or Mega Bangna. That tells a driver at Suvarnabhumi whether to wait in the arrival hall or take the Bangna-Trad Highway now.
RainViewer shows Thai precipitation using data from the Thai Meteorological Department (TMD), the national weather service, which operates a network of weather radars across the country. The map refreshes with each new scan, about every 5 minutes. From Bang Phli Yai the map also covers Bang Na, Samut Prakan and Suvarnabhumi.
The heaviest rain falls from August to October, when sea-breeze storms and monsoon rain combine. Bangna-Trad Highway and Kingkaew Road slow to a crawl, and low sois near the canals flood.
Heat builds storms before the rains and the monsoon ends unevenly. Short cells can interrupt airport transfers and factory shifts.
Rain is uncommon and the weather is stable. Airport pick-ups and trucking run with fewer weather delays.
Airport transfers and taxi queues suffer when a cell sits on the approach roads. The radar shows whether the transfer will be wet.
Shift workers ride in company buses and motorbikes along Kingkaew Road. A cell at shift change soaks the road, and the radar shows whether to leave now.
The Bangna-Trad Highway slows in heavy rain, and low sections flood. Time the drive to the gap between cells.
Shoppers at Mega Bangna time the walk to the car park. The radar shows whether the cell clears in 15 minutes.
Visitors to the temple and its large reclining Buddha need a dry walk across the open grounds. Check the radar before you go.
Heavy rain slows the roads to Suvarnabhumi Airport and queues taxis at the arrival level. Rain falls in slow cells that can sit over the approach roads. RainViewer shows when one clears.
Yes, heavy rain slows the Bangna-Trad Highway and floods low sections near Bang Phli. Trucks and buses queue behind it. Check the radar before leaving.
Yes, Bang Phli Yai floods when heavy cells fall on a flat plain with canals and fish ponds, and low sois near Kingkaew Road go first. Drains fill in the first hour. Avoid them during the downpour.
December to February is the driest, which suits the temple and the shopping centres best. March and April are hot with brief storms. August to October is the wettest.
Sea-breeze storms from the Gulf reach the south-east first and combine with heat from the airport and factories to build cells. A cell is often only a few kilometres wide. A hyperlocal radar shows the cell's track.
RainViewer shows live precipitation over Bang Phli Yai using Thai Meteorological Department radar data, refreshed about every 5 minutes. It shows rain as it falls, not a modelled prediction, and is a hyperlocal radar for the plain.
Yes, a rain alert warns you minutes before rain reaches a saved place such as the airport pick-up point or the factory gate. The 5-minute forecast timeline shows the next two hours. That settles whether to leave now.
A shift change on Kingkaew Road and a pick-up at Suvarnabhumi both depend on a dry gap, and RainViewer shows the next one.
Rain in Bang Phli Yai arrives as slow cells off the Gulf over a flat plain, and the gap between two cells is the window that matters.
RainViewer Essential gives you:
Two hours of 5-minute steps let you time the airport run.
Put an alert on the factory gate. RainViewer warns you minutes ahead, which settles whether to send the shift bus now.
Rain reaches Bang Phli most often from the south-west across the Gulf, so the arrows show whether a cell heads for the airport.
The 48-hour history shows what fell on the canals, which explains the wet road.
Track Bang Phli Yai, Suvarnabhumi and Mega Bangna at once.
Your weather app says showers for Samut Prakan this afternoon. A live hyperlocal radar shows the cell is over Kingkaew Road while Mega Bangna is dry, and that decides the shift bus.
