Thailand in July: Weather, Crowds and What to Expect
· 1 min read Practical
Thailand’s geography creates distinct regional weather patterns — the Andaman Coast (Phuket, Krabi, Koh Phi Phi) and Gulf Coast (Koh Samui, Koh Phangan) have opposite monsoon seasons. Understanding which applies to your destination in July is the key planning question.
Weather in July
Gulf Coast in its summer dry spell — excellent for Koh Samui, Koh Phangan, and Koh Tao. Andaman Coast is in monsoon. A tale of two coastlines.

Frequently Asked Questions
- Is July good for Koh Samui?
- Yes — Koh Samui and the Gulf islands are in their dry inter-monsoon season in July (and August). The weather is sunny, seas are calm, and the Full Moon Party on Koh Phangan is a big draw. Very good conditions for the Gulf islands in July.
- Is Koh Phi Phi open in July?
- Koh Phi Phi is open in July but the Andaman monsoon brings heavy rains and rough seas. Ferries still run but can be disrupted. The island is quieter and accommodation is very cheap — good for budget travellers who don't mind rain.
- What is the best Thai island in July?
- Koh Samui, Koh Phangan, and Koh Tao (Gulf of Thailand coast) are the best choices in July — they are dry and sunny when the Andaman Coast is wet. The Full Moon Party in July is particularly popular.
