Monthly Travel Guide
Thailand in June
June is solidly low season for the Andaman coast and Central Thailand, with the southwest monsoon in full effect. The Gulf coast continues to provide a relatively dry haven, though some showers begin appearing. Northern Thailand sees regular rain but with spectacular green landscapes and far fewer tourists. Prices are at their lowest across popular Andaman resorts, and accommodation quality-to-price ratios are excellent for travellers who don't mind occasional rain.
Weather by Region
North (Chiang Mai)
Warm and rainy. Chiang Mai averages 25–34°C with regular afternoon rain. Waterfalls are at their most impressive and the countryside is vivid green.
Central (Bangkok)
Rainy season. Bangkok sees daily afternoon showers. Temperatures 27–34°C. Flash flooding is possible in low-lying areas.
South — Gulf Coast
Mostly dry with increasing afternoon showers. Koh Samui water temperature peaks around 30°C. Still a good beach destination.
South — Andaman Coast
Full monsoon. Phuket, Krabi, Koh Lanta see heavy rain and rough seas. Many tourist businesses close or reduce hours. Red flag warnings frequent on beaches.
Best Destinations in June
Gulf coast stays largely dry while the rest of Thailand is wet — good beach weather at low-season prices.
Lush green trekking landscapes and some of the cheapest accommodation rates of the year.
Museums, shopping malls, and indoor attractions make Bangkok viable year-round. Cheap hotel rates in June.
Where to Avoid in June
Koh Lanta
Island effectively closes for the season — many resorts shut, ferry service reduced.
Koh Phi Phi
Rough seas and heavy rain make this a poor choice; most dive operations suspended.
