Koh Samui in July

What to expect on Koh Samui in July?

6+ hours of solid daily sunshine! The average July temperature on Samui is a more-than-acceptable 29.25 degrees Celsius (84.65°F). Since 2003, the coldest it ever dropped was 22°C/72°F – not exactly jacket weather, even then.

Is July a good time to visit Koh Samui?

Tremendously so.

Quick note: You’ll run into information stating that July is rainy season in Thailand. While July is a pretty wet month on Phuket (an average of 19 days of 31), Oct/Nov/Dec are Koh Samui’s rainy season – not July.

Instead, expect the occasional (and quite spectacular) tropical storm. These usually come in the form of “afternoon showers”, and they’re nothing to dread. They don’t last long and are an extremely refreshing, often dramatic, experience. Seriously – rain – not a problem. It will be sunny plenty of the time.

I recommend that every visitor to Koh Samui expect at least some rain – if you’re prepared, or even looking forward to it, a short tropical storm can be another great part of your Samui holiday. Really!
