The quick answer
Do not judge Koh Samui weather only by the rain icon. Check the sky, wind, waves, live beach views, and boat-trip conditions before changing your plans.
Rain is not the full story
A rainy forecast does not always mean the whole island is bad. Samui weather can change by area and time of day.
Boat trips need extra checks
For Pig Island, Ang Thong, Koh Tao, and private boats, wind and sea conditions matter more than normal rain.
Use live beach views
Live webcams can show the real sky, beach, and sea conditions better than a normal weather app.
