Koh Samui in June: Weather, What to Expect and 12 June FAQs

Honestly, I can’t wait for June. Though I’m a grown adult, I still associate June with the start of summer vacation, endless days of swimming, and practically living on popsicles and ice cream. Remember the days?

Koh Samui in June will easily accommodate all three of the above activities – and pretty much anything else you need from a perfect early summer break.

Choose Samui over Phuket in June (or always, y’know, just to foster an unwarranted bias…). Koh Samui and Phuket’s different climates catch many travellers out. Sun-seekers will be better off in Phuket at some times of the year, but June is not one of them.

7. Will it rain in June?

Koh Samui in June: Weather, What to Expect and 12 June FAQs

Probably! A short, sharp tropical shower isn’t unusual – a great excuse to cool off under an umbrella or on a deck with a good book and a cold Thai beer. Taking averages at face value, June has less rainfall (by volume) than May or July but it occurs over a similar time period.
