Rain in Phuket: What You Need to Know
Phuket rain arrives off the Andaman Sea and it does not announce itself gradually. The southwest monsoon from May to October pushes squalls onshore that can deliver 80-100mm in a single afternoon event. The central mountain ridge running north to south along the island's spine creates an orographic effect - the west coast (Patong, Karon, Kata) catches moisture directly off the sea, while the east coast (Rawai, Chalong Bay) can stay relatively dry in the same storm.
The most common urgent use of a radar app in Phuket is ferry departure planning. The Rassada pier (for Phi Phi, Koh Yao) and Ao Makham pier both operate in conditions that change within the hour. A squall forming 15-20km offshore is visible on the radar long before it reaches the pier - enough time to decide whether to board or delay.
RainViewer shows you storm cells moving onshore before they arrive, with direction arrows showing their track.
RainViewer Radar Coverage in Phuket
RainViewer combines Andaman coast radar for Phuket. From here, the same map shows rain approaching from Phang Nga, Krabi, and the open Andaman - useful if you're driving between the airport and the beach zones or taking ferries to the outer islands.
Wet season (May-October)
The southwest monsoon is the dominant rain driver. June and September are typically the wettest months, with October bringing intense late-season events. Red flag days on beaches during this period are common when combined seas and wind accompany rain.
Shoulder months (May and October)
May is the season transition when the monsoon establishes itself. Conditions can be clear in the morning and violent by 2pm. October trails off but remains volatile.
Dry season (November-April)
Phuket's peak tourist season aligns entirely with the dry window. Even in dry season, isolated showers develop - they appear clearly on the radar well before arrival.
Why You Need a Rain Radar in Phuket
Deciding whether to take the Phi Phi ferry
The Rassada pier-Phi Phi route takes 1.5 hours across exposed Andaman waters. A squall forming offshore can close the route mid-crossing or at departure. Seeing the storm track on the radar before driving to the pier is the single most useful planning step.
Planning Patong or west coast beach activities
The west coast catches the brunt of the southwest monsoon. A beach that's fine at 10am can be under a red flag by 1pm. Checking the radar at breakfast tells you whether the morning window holds for the whole day.
Managing hotel pickup and guest transport during storms
Resort drivers need to know whether a guest pickup from the airport will coincide with a heavy cell on Route 402. A 30-minute warning is enough to reroute or delay departure.
Timing dive boat departures from Chalong Bay
Dive trips depart at 7-8am for sites in the Similan islands. Conditions at departure don't always predict conditions at the dive site. Checking the offshore radar track tells the dive master whether a system will intercept the route.
Phuket Rain Radar: Frequently Asked Questions
- How often does the RainViewer map update for Phuket?
Every 5 minutes. During active southwest monsoon squalls that move fast, this frequency is the most useful tool available.
- Is Phuket's rainy season worth avoiding for travel?
Many visitors do, but mornings are often clear. The key is using the radar to identify the dry windows within each day rather than writing off the whole trip.
- Can RainViewer show me offshore storm cells approaching Phuket?
Yes. The radar network covers open sea areas around Phuket, and RainViewer shows offshore cells with direction arrows indicating their track.
Track Rain in Phuket in Real Time
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.
RainViewer 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. RainViewer tells you whether the Andaman is clear enough to board now or wait an hour for the squall to pass.
