🏖️ Beach & relaxation trips
For a great beach holiday in Southeast Asia, the month matters more than the destination: the same island can be perfect in January and monsoon-soaked in August. The golden rule? Follow the two coasts — Gulf of Thailand in summer, Andaman Sea in winter.
Tip: Aim for at least 6h of sun a day and 26°C water: the green-rated destinations below meet those criteria for your month.
