Live Rain Radar for Phuket
Monitor rain and storms across Phuket and the Andaman coast in real time. Updated every 5 minutes.
Local Weather Context
Phuket is Thailand's largest island, exposed to the Andaman Sea on its western coast. The island's weather is governed by two monsoons: the southwest monsoon brings heavy rain and rough seas from May to October, whilst the northeast monsoon (November–April) delivers the dry season that drives peak tourism. Storms approach from the Andaman Sea with little warning due to the open ocean fetch.
Seasons
Wet season (May–October)
Southwest monsoon drives sustained heavy rainfall, often exceeding 300 mm per month from August–October. Western beaches (Patong, Kata, Karon) face large swells and dangerous rip currents. Afternoon storms are near-daily occurrences, sometimes lasting several hours.
Transition months (November, April)
November sees seas calming as the southwest monsoon retreats. April brings building heat and humidity before monsoon onset, with occasional thunderstorms.
Dry season (December–March)
Northeast monsoon keeps skies clear and seas calm. Rainfall drops below 50 mm per month. This is high tourist season with 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 shows squall lines approaching from the Andaman Sea hours in advance.
Beach tourists
Visitors to Patong, Kata, and Karon beaches use radar to decide between morning beach time and afternoon indoor activities during wet season.
Yacht and marina operators
Phuket's marinas at Boat Lagoon and Royal Phuket Marina monitor radar for approaching storms that require securing vessels.
Construction workers
Phuket's ongoing construction boom means thousands of outdoor workers need storm warnings to ensure safety on exposed building sites.
Radar Coverage
RainViewer 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 StewartI 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 shows rain cells approaching Phuket from the west, typically giving 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 all day, and radar helps you find dry windows 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 departing to ensure no squall lines are crossing your route.
See the squall before it closes the ferry pier
Phuket's rain arrives off the Andaman without warning and doesn't follow Bangkok's forecast. The map updates every 5 minutes — often 2–5 minutes faster than other apps — so by the time a squall is 15km offshore, you've already seen it tracking toward the pier.
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 squall passes Rassada pier and the Phi Phi or Koh Yao crossing is workable again
- Rain alerts that trigger before 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 when the animation is unclear, you can see whether the offshore cell is tracking toward Patong or swinging north toward Phang Nga
- 48 hours of radar history — see how yesterday's monsoon squall moved across the island's ridge and recognise the same pattern building offshore today
- Multiple locations — track rain at Rassada pier, Patong Beach, and the Similan dive route at the same time
A 7-day forecast tells you June will be wet. Rain Viewer tells you whether the Andaman is clear enough to board now or wait an hour for the squall to pass.
