Koh Samui in August
Is August a good time to visit Koh Samui?
The Koh Samui Guide: “If we didn’t have this…I really don’t think we would have had such a great time” [bsc_button size=”lg” style=”primary” block=”false” title=”Get your Koh Samui Guide” url=”https://www.thekohsamuiguide.com/” target=”_blank” nofollow=”false”]
I first visited Koh Samui in August, 2003 and … clearly, it was a pretty good sales pitch. August is fantastic but – here’s the sneakiest of tips – the island completely empties on September 1st, as families head home for the start of school. If you want August’s fantastic weather, with beaches to yourself, see if you can stretch your trip into the first few days of September.
Is August or September better on Koh Samui?
- Temperature (avg): 29°C in August vs 28°C in September
- Sunshine (hours): 6 in August vs 6 in September
- Rainy days (avg): 10 days (100mm) in August vs 11 days (130mm) in September
- Sea temperature: 28°C in August vs 28°C in September
If you have the choice, I’d pick early September only because it will likely be quieter (kids back in school). As for differences in the weather, there’s really not much in it. However, early August tends to have nicer weather than late September. *data source

Koh Samui weather in August
How much does it rain on Koh Samui in August?
The big question: will it rain in August? It very well might – but you’re going to choose not to care. Why? Don’t fixate on the weather (something you can’t control) – Koh Samui is gorgeous always, as are its drinks, food and people.
Always expect rain in the tropics, but rest assured it never lasts very long. Plan some Koh Samui rainy day activities, just in case.
As with Koh Samui in July, afternoon showers are pretty common in August. Here’s an example:
August on Koh Samui: 3:55pm – perfect sunshine
4:12pm – storm comes out of nowhere
4:17pm – storm’s here!
Why to truly disregard the high probability of storms like this? See the plastic roll-down screen?
When the rain arrives you can almost always stay exactly where you are – enjoy the exact same hilarious company, cold beer and amazing Thai food.

If ‘humid’ immediately makes you think ‘hair’… consider adding a fix-it remedy to your toiletries bag: see my best recommendations for toiletries vs Thailand.
