Short answer
June is firmly in the Phuket monsoon: the Thai Meteorological Department's 1981–2010 normals give 213.3 mm of rain over 18.2 rainy days and a mean daily maximum of 32.4 °C. Phuket 101 rates the west-coast sea as rough with red flags common, so swimming from beaches needs care. Boat days still run in June, Maya Bay is open until 31 July, the Similan Islands are closed, and hotels are at their cheapest. A Phang Nga Bay day is the steadier option.
June has rain on most days, but rarely all day
June is wet but not the wettest. The Thai Meteorological Department's 1981–2010 normals for the Phuket station give 213.3 mm over 18.2 rainy days, a little less than May (259.5 mm) and July (258.2 mm). The mean daily maximum is 32.4 °C and the mean minimum 25.5 °C. The airport station in the north records 256.8 mm over 18.9 days. The newer 1991–2020 table on Wikipedia's Phuket City page gives 249.4 mm and 15.9 days with 1 mm or more, which is higher than the older figure.
Phuket 101 says it does not rain every day or all day in June, and that the rain tends to arrive in the evening, so mornings are often sunny and calm. The Thai weather service's climate summary notes that clear skies are seldom seen during the southwest monsoon, apart from a few days in June. Sunshine falls to 150 hours in the month, about 5 hours a day, in the Royal Irrigation Department's figures printed on Wikipedia's Phuket Province page.
Red flags and the west coast: the real June risk
The sea is the thing to respect. Phuket 101 rates June as rough on the west coast with red flags common, and says the swells come from the southwest. The Thai Meteorological Department says winds blow from the south, southwest and west during the southwest monsoon. Wikivoyage warns that strong currents on many beaches make drownings common in the monsoon, and records four tourists dying during a three-day stretch in June 2009. The water is warm, 30 °C according to Phuket 101, which makes it tempting.
The rule is simple: a red flag means no swimming, however good a swimmer you are. Phuket 101 says east-coast beaches such as Ao Po, Cape Panwa and parts of Rawai stay calmer, and that a hotel with a good pool is the sensible backup. Our guide to rip currents and red flags in Phuket explains the flag colours, and Phuket's rainy-day ideas cover the wet afternoons.
Does the James Bond Island tour run in June?
Yes, in the normal way. The details we hold for our James Bond Island and Phang Nga Bay canoe tour list no closed season. Phuket 101 says all attractions, tours and day trips usually run in June, with occasional stormy days when island speedboats are cancelled, which it describes as not frequent. The day is from $85 per person, about 8.5 hours, with hotel pickup between about 7:00 and 8:00 am and the boat leaving Laem Nga pier at about 9:00.
The decision to sail belongs to the operator. If the sea is unsafe, the operator moves the trip to another date or refunds it, so keep a spare day in your plans. The day is protected by the geography: Phuket 101 says the limestone cliffs shield Phang Nga Bay from the monsoon swell. The park fee is included in the price, which means no cash is needed at the gate. See our James Bond Island in the rainy season guide for the sea in more detail.
A canoe day under June clouds
Rain changes the look of the day more than its plan. Phuket 101 says the scenery in Phang Nga Bay is even more impressive with big clouds above the limestone cliffs, and its rainy-season tips say some tours, Phang Nga Bay among them, are nicer with heavy clouds. On our tour the paddler does the work in the canoe, so wet weather does not demand effort from you, but you will want a dry bag for your phone and a change of clothes.
Two parts of the day are tide-dependent, whatever the month. Low tide can change the order of the stops or shorten the canoe route into the lagoon, and James Bond Island gets busy around midday, so the guide times the stop around the tide and the crowds. Bring swimwear, a towel (towels are not included), sunscreen and a hat as well as a rain layer; the sun still appears between showers, and the UV index stays extreme according to Phuket 101.
What is closed in June, and what is open
The Similan and Surin Islands are closed in June, as Phuket 101 notes, so the longest island days from Phuket are off the table until mid-October. Our Similan day runs only from 15 October to 14 May. The other classics stay open. Maya Bay on Phi Phi Leh is open in June and closes on 1 August, so June is still a month in which you can land on the beach, in rounds of up to 375 people an hour.
Our Phi Phi and Maya Bay speedboat tour is from $75 per person; the open-sea crossing can be bumpy and the national park fee of 400 baht per adult and 200 per child is collected in cash by the operator. Phuket 101 says Phi Phi ferries still operate in June and speedboat trips are cancelled only on stormy days. If your stomach is sensitive, our guide to seasickness on speedboat tours helps.
Prices, crowds and events in June
June is cheap for rooms. Phuket 101 says hotel prices drop significantly, a luxury hotel becomes affordable, and many hotels add free breakfast, spa credits or upgrades, while food, tours and shopping prices stay about the same. The island is not empty: the Phuket Tourism Authority put average hotel occupancy at 62.63 percent for June 2025, according to a Pattaya Mail report of a July 2025 briefing. So the island is quieter in June, not empty.
For events, Phuket 101 lists the Phuket Baba Wedding in Old Phuket Town, a traditional event that celebrates the descendants of marriages between Chinese immigrants and local women, with costumes and ceremonies. Wikipedia's list of Thai public holidays gives 3 June as Queen Suthida's Birthday. The dates of local festivals change each year, so check the date for your trip rather than building a plan on it.
Who June suits, and who should wait
June suits travellers on a budget, people who like a quiet Old Town and a green island, and visitors who treat rain as part of the trip. It suits the Phang Nga Bay day well, as the steadier sea in the sheltered bay is the point. It suits surfers too: Phuket 101 says June monsoon swells bring consistent waves at Kata, Kalim and Surin.
It does not suit anyone who needs a calm west-coast beach, a guaranteed Similan day or a fixed schedule with no spare day. Our speedboats are closed to pregnant women, infants under 1 year and guests over 70. For the months either side, see Phuket in May and Phuket in July, and for the whole season read our guide to travelling in the rainy season.
Practical checklist
- Treat a red flag as a ban on swimming at that beach, whatever your level.
- Keep a spare day in your plans in case the operator moves a boat trip for the sea.
- Pack a rain layer, a dry bag, waterproof sandals and a change of clothes for the boat.
- Choose a hotel with a good pool, since beach swimming may be unsafe.
- Ask us to confirm your Phang Nga Bay date on WhatsApp before you pay.
