Live Rain Radar for Phuket
Monitor rain and storms across Phuket and the Andaman coast in real time. Updates every 5 minutes.
Local Weather Context
Phuket is Thailand’s largest island, situated on the Andaman Sea along its western coastline. The island’s weather is shaped by two monsoon systems: the southwest monsoon brings heavy rain and rough seas from May to October, while the northeast monsoon (November–April) ushers in the dry season that attracts peak tourism. Storms can approach from the Andaman Sea with little warning due to the open ocean exposure.
Seasons
Wet season (May–October)
The southwest monsoon brings prolonged heavy rainfall, often exceeding 300 mm per month from August to October. Western beaches (Patong, Kata, Karon) experience large swells and hazardous rip currents. Afternoon storms are almost daily, sometimes lasting several hours.
Transition months (November, April)
In November, the seas begin to calm as the southwest monsoon withdraws. April sees rising heat and humidity ahead of the monsoon’s arrival, with occasional thunderstorms.
Dry season (December–March)
The northeast monsoon keeps skies clear and seas calm. Rainfall drops below 50 mm per month. This is peak tourist season, offering ideal beach and diving conditions.

Who Needs Rain Radar Here
Dive and Tour Operators
Boat trips to Phi Phi Islands, Similan Islands, and James Bond Island require weather monitoring. Radar displays squall lines approaching from the Andaman Sea hours in advance.
Beach Tourists
Visitors to Patong, Kata, and Karon beaches use radar to decide between a morning on the beach and afternoon indoor activities during the wet season.
Yacht and Marina Operators
Phuket’s marinas at Boat Lagoon and Royal Phuket Marina monitor radar for approaching storms that require vessels to be secured.
Construction Workers
Phuket’s ongoing construction boom means thousands of outdoor workers need storm warnings to ensure safety on exposed building sites.
Radar Coverage
Rain Viewer provides coverage across the entire island and the surrounding Andaman Sea, extending to Phang Nga Bay and Krabi. Offshore coverage means storms approaching from the west are visible well before they reach Phuket’s beaches.
What Our Users Say
-
“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”
Duncan Stewart -
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.

FAQ
Can radar track storms coming from the Andaman Sea?
Yes. Offshore radar coverage displays rain cells approaching Phuket from the west, usually providing 30–60 minutes’ advance warning before they reach the coast.
Is Phuket's wet season really that rainy?
Yes — monthly rainfall can exceed 300 mm. However, rain often falls in intense bursts rather than lasting all day, and radar helps you spot dry intervals for activities.
Does radar cover the trip to Phi Phi Islands?
Coverage extends across the waters between Phuket and Phi Phi. Check the radar animation before setting off to ensure no squall lines are crossing your route.
Spot the squall before it shuts the ferry pier
Phuket’s rain sweeps in from the Andaman with no warning and doesn’t follow Bangkok’s forecast. The map updates every 5 minutes — often 2–5 minutes quicker than other apps — so by the time a squall is 15km offshore, you’ve already seen it heading towards the pier.
Rain Viewer Essential gives you:
- A 2-hour rain forecast in 5-minute intervals — not hourly blocks, so you can see the precise window when the squall passes Rassada pier and the Phi Phi or Koh Yao crossing is safe again
- Rain alerts that trigger before the rain arrives — set the ferry pier, your beach resort, or Chalong Bay and get notified while you can still change your plans
- Direction arrows on the map — so even if the animation isn’t clear, you can see whether the offshore cell is heading for Patong or swinging north towards Phang Nga
- 48 hours of radar history — see how yesterday’s monsoon squall crossed the island’s ridge and spot the same pattern forming offshore today
- Multiple locations — track rain at Rassada pier, Patong Beach, and the Similan dive route all at once
A 7-day forecast tells you June will be wet. Rain Viewer tells you whether the Andaman is clear enough to board now or if you should wait an hour for the squall to pass.
