Rain in Hat Yai: What You Need to Know
Hat Yai is the commercial heart of southern Thailand and one of its flood-prone cities: the U-Tapao canal runs through it, and November rain can put the shopping streets under water. Floods in November 2010 and November 2025 are the events locals use as the benchmark, and the 2025 rain was described in news reports as the heaviest in 300 years. A Hat Yai rain radar shows whether a monsoon band is still building over the catchment or already breaking up.
Moist air from the Gulf of Thailand rises over the Sankalakhiri range behind the city, so rain collects in the U-Tapao basin and runs into Hat Yai through the canal. The city sits on a low plain between the hills and Songkhla Lake with little slope to drain it. A standard forecast for Songkhla province gives a total, not a timing, which is why hyperlocal radar matters so much here.
RainViewer shows precipitation over Hat 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 the next band is feeding the catchment behind the city or passing towards Songkhla.
RainViewer Radar Coverage in Hat Yai
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 Hat Yai the map also covers Songkhla, Sadao and Phatthalung.
Northeast monsoon season (October to January)
November is the key flood month, when persistent monsoon rain and a deep trough can bring heavy falls for days. Water from the U-Tapao canal enters Hat Yai Nai, Kim Yong Market and the streets around the railway station, and traffic on the main roads stops.
Transition months (February to April)
Monsoon rain fades but unsettled showers continue, and the first heat thunderstorms come in April. Rain becomes less regular and harder to forecast.
Drier months (May to September)
The southwest monsoon brings lighter, shorter showers to the east coast than to the Andaman side. This is the safest period for travel and outdoor work in and around the city.
Why You Need a Rain Radar in Hat Yai
Shopkeepers at Kim Yong Market and Hat Yai Nai
Shopkeepers along the market streets lift stock when the canal rises. The radar shows whether the band over the catchment has more rain to deliver.
Drivers on Phetkasem Road and the Hat Yai bypass
The main roads flood at the underpasses first. Time the drive to the gap in the rain.
Hat Yai Junction railway travellers
Trains to Bangkok and Padang Besar leave Hat Yai Junction, and floods can cancel services. Check the radar before heading to the station.
Prince of Songkla University students and staff
The Hat Yai campus at Kho Hong has hillside roads that run with water in a downpour. Plan the commute around the dry gap.
Hat Yai Municipal Park and Songkhla Lake visitors
Visitors to Hat Yai Municipal Park and the Songkhla lakeshore want a dry gap for the cable car and the lake road. The radar shows whether it is worth leaving.
Hat Yai Rain Radar: Frequently Asked Questions
- How does rain affect trade in Hat Yai?
Floods from the U-Tapao canal shut Kim Yong Market and the shopping streets of Hat Yai Nai, and November floods in 2010 and 2025 closed shops for days. Rain in the catchment arrives hours before water does. RainViewer shows the band building.
- Does rain affect Phetkasem Road and the Hat Yai bypass?
Yes, heavy rain floods the underpasses on Phetkasem Road and slows traffic on the Hat Yai bypass. Water collects at the low junctions in the first hour. Check the radar before driving.
- Does Hat Yai flood when it rains?
Yes, Hat Yai floods when monsoon rain fills the U-Tapao canal, as in November 2010 and November 2025. Hat Yai Nai and the streets around the railway station go under first. Move vehicles and stock to higher floors early.
- When is the best time to visit Hat Yai to avoid rain?
May to September is the driest and the safest, with March to April hot and mostly dry. November is the worst for floods. Avoid the northeast monsoon from October to January for flood-sensitive travel.
- Why does it flood in Hat Yai when rain falls in the hills?
Rain falling on the Sankalakhiri range collects in the U-Tapao basin and reaches the low plain through the canal hours later. The city can be dry while its water is rising. A hyperlocal radar shows the rain upstream.
- How does RainViewer's radar work in Hat Yai?
RainViewer shows live precipitation over Hat 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 basin.
- Can RainViewer warn me before rain hits Hat Yai?
Yes, a rain alert warns you minutes before rain reaches a saved place such as Kim Yong Market or the railway station. The 5-minute forecast timeline shows the next two hours. That settles whether to raise stock now.

A shop at Kim Yong Market and a drive down Phetkasem Road both depend on knowing what the next band brings, and RainViewer shows it.
