🌀️ Cool Season | November to February

Koh Hong

Best overall time to visit

Why visit during this season

  • Comfortable temperatures and lower humidity
  • Little rain and clear skies
  • Ideal conditions for sightseeing, beaches and outdoor activities

This is Thailand’s most popular travel period, especially over December and January.

Best areas to visit

  • Bangkok & Central Thailand – Sightseeing is far more pleasant without extreme heat
  • Northern Thailand (Chiang Mai, Chiang Rai, Pai) – Cooler evenings and great hiking conditions
  • Andaman Coast (Phuket, Krabi, Koh Lanta) – Calm seas and excellent snorkelling
  • Gulf Islands (Koh Samui, Koh Phangan, Koh Tao) – Warm water and beach-perfect days

Things to keep in mind

  • Higher prices and limited availability around Christmas and New Year
  • Book accommodation and transport early

πŸ”₯ Hot Season | March to May

Best for beaches and fewer crowds

Why visit during this season

  • Long sunny days and very little rain
  • Perfect sea conditions for swimming and snorkelling
  • Fewer international tourists than peak season

Temperatures can be intense, especially inland, but coastal areas are far more manageable.

Best areas to visit

  • Islands and coastal regions – Sea breezes make the heat more bearable
  • Koh Tao & Koh Phangan – Excellent visibility for diving and snorkelling
  • Krabi & Railay – Beach time, boat trips and sunset views
  • Gulf of Thailand islands – Slightly less extreme heat than inland areas

Things to keep in mind

  • Midday sightseeing can be exhausting
  • Plan activities early morning or late afternoon
  • Songkran (Thai New Year) in April brings crowds but is an unforgettable experience

🌿 Rainy or Green Season | June to October

Best for landscapes, value and slower travel

Why visit during this season

  • Lush green scenery and dramatic skies
  • Fewer tourists and better accommodation deals
  • Rain usually falls in short bursts, not all day

This season is often misunderstood β€” it can be a great time to travel if you choose the right regions.

Best areas to visit

  • Gulf Islands (Koh Samui, Koh Phangan, Koh Tao) – Drier than the west coast
  • Northern Thailand – Green hills, waterfalls and fewer crowds
  • Bangkok – Great food scene and indoor attractions regardless of weather

Areas to avoid at this time

  • Andaman Coast (Phuket, Krabi, Koh Phi Phi) – Rough seas and limited boat access

Things to keep in mind

  • Occasional flooding in some regions
  • Boat schedules can change due to sea conditions
  • Flexible plans work best during this season

🌴 So, When Is the Best Time to Visit Thailand?

  • For first-time visitors: November to February
  • For beach lovers: March to May or Gulf Islands during rainy season
  • For budget travellers: June to October
  • For fewer crowds and greenery: Late rainy season into early cool season

Thailand truly offers something in every season β€” it’s just about matching the time of year to the experience you want.
