When should you go to Thailand? This month-by-month guide covers the weather, the peak and green seasons, the cheapest months, and the best timing for beaches versus city sightseeing — tailored for travellers from India.
Quick answer
The best overall time to visit Thailand is November to March — dry, sunny and perfect for beaches and islands. For the lowest prices, travel in the green season (June–October).
Peak season (Nov–Mar)
Cool, dry and ideal weather for Bangkok, Pattaya, Phuket and the islands. It’s the busiest and priciest period, so book flights and hotels early.
Hot season (Apr–May)
Very hot and humid, but a good time for water festivals (Songkran in April) and lower crowds before the rains.
Green season (Jun–Oct)
Short afternoon showers, lush scenery and the best deals on flights and hotels. Mornings are often clear — great value if you don’t mind some rain.
Best time by destination
Bangkok & Pattaya: year-round (Nov–Mar best). Phuket & Krabi (Andaman coast): Nov–Apr. Koh Samui (Gulf coast): best Feb–Sep, as its rains come later.
Cheapest months
June, September and October typically have the lowest fares from India. Pair them with a Thailand package from Kolkata for the best value — and see the full Thailand trip cost breakdown.
