Live Rain Radar for Prachuap Khiri Khan
Monitor rain across Hua Hin, Prachuap, and the narrow isthmus coast. Updated every 5 minutes.
Local Weather Context
Prachuap Khiri Khan province occupies Thailand's narrowest point — just 13 km between the Gulf of Thailand and the Myanmar border. This unique geography means weather systems from both the Gulf and the Andaman side can affect the province. Hua Hin, the royal beach resort, and Prachuap city sit directly on the Gulf coast with mountains rising sharply behind them.
Seasons
Wet season (May–November)
Both monsoons affect this narrow isthmus. The southwest monsoon (May–October) brings rain from the Andaman side over the mountains, while the northeast monsoon onset (October–November) adds Gulf moisture. September–November can see 200+ mm per month.
Transition months (December, April)
December sees the monsoon tapering off. April brings pre-monsoon heat with occasional afternoon thunderstorms building over the mountains.
Dry season (January–March)
Pleasant weather with minimal rainfall — under 30 mm per month. Hua Hin enjoys its peak season with clear skies and gentle breezes from the Gulf.

Who Needs Rain Radar Here
Hua Hin tourists and residents
The resort town's outdoor lifestyle — golf courses, beach clubs, night markets — depends on dry weather windows. Radar helps plan activities around tropical showers.
Pineapple and coconut farmers
Prachuap Khiri Khan is Thailand's largest pineapple-producing province. Farmers use radar to time harvesting and transportation of this rain-sensitive crop.
Fishing communities
Small-scale fishermen along the coast from Hua Hin to Bang Saphan monitor radar to avoid squalls while at sea.
Royal Thai Air Force
Wing 5 at Prachuap air base requires accurate weather monitoring for flight operations along the coast.
Radar Coverage
RainViewer covers the entire narrow province, from Hua Hin in the north to Bang Saphan in the south. Gulf of Thailand coverage shows approaching storms, and the narrow width of the province means weather from the Andaman side can also be tracked as it crosses the mountains.
Lo que dicen nuestros usuarios
“A veces es un poco entusiasta con las predicciones de lluvia, pero es precisa y confiable en las imágenes de radar, y es la única app de radar que he conservado y no he desinstalado”
Duncan StewartDebo cambiar mi opinión una vez más, esta sigue siendo la mejor app de meteorología en la tienda de aplicaciones. El problema que tenía era con mi teléfono y no con esta aplicación de primera categoría. Una parte que realmente me gusta son los widgets.

FAQ
Why does Prachuap Khiri Khan get rain from both sides?
The province is only 13 km wide at its narrowest point. Weather systems from both the Gulf of Thailand (east) and the Andaman Sea (west, crossing Myanmar) can bring rain here.
Is radar reliable for Hua Hin's weather?
Yes. Radar provides excellent coastal coverage, showing Gulf storms approaching the shore well in advance. Mountain-generated storms from the west are also visible as they cross the ranges.
Can I track weather for a golf game in Hua Hin?
Radar is perfect for this. Check the animation 30 minutes before tee time to see if any rain cells are heading toward the course.
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.
