Live Rain Radar for Prachuap Khiri Khan
Track rain across Prachuap Khiri Khan in real time with Rain Viewer, a hyperlocal rain radar app, updated every 5 minutes, street by street.
Local Weather Context
Prachuap Khiri Khan is the narrowest part of mainland Thailand — at its waist near the Burmese border, the country is only 10km wide. This geography puts the province in an unusual dual-exposure position: southwest monsoon rain arrives from the Gulf side May to October, and a tail of the northeast monsoon reaches the coast from November to December.
Hua Hin is Bangkok's closest beach resort and attracts enormous weekend traffic. The Saturday afternoon storm that floods Hua Hin's main street during monsoon season affects thousands of visitors who drove down from Bangkok that morning. A radar check before the drive south changes how the day is planned.
Seasons
Southwest monsoon (May–October)
Primary wet season, afternoon storms.
Northeast monsoon tail (November–December)
Lighter secondary wet period.
Dry season (January–April)
Peak tourist season for Hua Hin, minimal rain.

Use Cases
Timing a Hua Hin beach weekend from Bangkok
A cell sitting over Hua Hin on arrival means a flooded main street. Checking the radar before departure shows whether the Saturday window is clear.
Planning coastal activities at Khao Sam Roi Yot National Park
The park's caves and trails require dry conditions. Checking the radar before driving south from Hua Hin avoids arriving at a flooded cave entrance.
Managing the Highway 4 drive during the dual monsoon window
During October–December, the transition between southwest and northeast rain creates unpredictable conditions on the coastal highway.

“有时对雨的预测略显热情，但雷达图像准确无误，这是我唯一保留并未卸载的雷达应用”
Duncan Stewart“我必须再次更改我的反馈，这仍然是应用商店里最好的大脑应用，我的问题在于我的手机而不是这个顶级应用，我真的很喜欢其中的小部件。”

FAQ
How often does the Rain Viewer map update for Prachuap Khiri Khan?

Does Prachuap Khiri Khan have a dry season?
Yes — January through April is the most reliable dry period and Hua Hin's peak tourist season. The dual-monsoon exposure means the wet window extends longer than most of central Thailand.
See rain in Prachuap Khiri Khan before it floods Hua Hin
Prachuap's rain comes from two directions and doesn't follow Bangkok's weekend forecast. The map updates every 5 minutes — often 2–5 minutes faster than other apps — so by the time a Gulf cell is forming off Hua Hin, you've already seen it before you leave the city.
Rain Viewer Essential gives you:
- A 2-hour rain forecast in 5-minute slices — not hourly blocks, so you can see the exact window when the storm clears the main street and the beach or cave trail is accessible again
- Rain alerts that trigger before rain arrives — set Hua Hin beach, Khao Sam Roi Yot, or your Highway 4 departure point and get notified while you can still adjust your plans
- Direction arrows on the map — so even when the animation is unclear, you can see whether the Gulf cell is tracking toward Hua Hin or moving south toward Chumphon
- 48 hours of radar history — see how last weekend's storm moved down the coast and recognise the same pattern forming this Saturday morning
- Multiple locations — track rain at your Bangkok starting point, Hua Hin beach, and Khao Sam Roi Yot at the same time
A 7-day forecast tells you October will be unpredictable. Rain Viewer tells you whether the drive south is worth it today or better left to Sunday.
