VerdictNovember to February
The short answer

The best time to visit Thailand is November to February

For most travellers, November to February is ideal — cool, dry and sunny across the country and the best beach weather on the Andaman coast (Phuket, Krabi). March to May is hot but great value; June to October is the green season with lower prices and short daily showers. The Gulf islands (Koh Samui) run slightly later, so we match your islands to your dates.
