🇹🇭 Weather Forecast for Thailand
🗓 Friday, 5 June 2026

🗣️ Thailand continues to be affected by a rather strong southwesterly monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand, together with a low-pressure cell over upper Vietnam. This will cause thunderstorms to increase in many areas, with isolated heavy rain, especially in the North, upper Northeast, East, and southern Andaman coast. Meanwhile, the Andaman Sea and the upper Gulf of Thailand will have rather strong waves. Small boats should navigate with extra caution.

🌡️ General Weather Conditions and Hazards

☀️ General Weather Conditions
The rather strong southwesterly monsoon remains the main factor influencing Thailand’s weather. It will cause scattered thunderstorms in many areas, with isolated heavy rain, especially in the North, East, lower Central region, and southern West Coast. People should closely monitor weather conditions during this period.

⚠️ Risk Warning
People should beware of accumulated heavy rainfall, which may cause flash floods, forest runoff, and landslides, especially in foothill areas, low-lying areas, and places near waterways.

🌊 Water Situation and Disasters

📊 Overall Water Situation
Thailand has fully entered the rainy season since mid-May. Early June is a period when rainfall is becoming more continuous, especially in the East and the southern Andaman coast. As a result, water levels in many reservoirs are gradually increasing.

⚠️ Areas to Monitor
📍 Western side of the North — Risk of forest runoff in foothill areas.
📍 Eastern Region — Watch for waterlogging and runoff from accumulated rainfall.
📍 Bangkok and surrounding provinces — Watch for short-term flooding from heavy rain during the evening to night.
📍 Southern Andaman coast — Monitor strong waves and continuous heavy rain.

🚨 Disaster Alerts
The National Disaster Warning Center (NDWC) has not issued any severe nationwide disaster warning. However, people in risk areas are advised to continue monitoring news updates and warning announcements closely.

😷 PM2.5 and Air Quality Situation

📡 Overall Air Quality
Continuous rainfall helps reduce PM2.5 dust accumulation in many parts of the country, keeping overall air quality mostly at a good to moderate level. However, some northern provinces may still experience elevated dust levels at certain times, especially in the morning.

🔎 PM2.5 Watch Areas
📍 Chiang Mai
📍 Chiang Rai

Meanwhile, the South continues to receive rain from the influence of the moderate southwesterly monsoon, with more rain along the Andaman coast than the Gulf coast.

⚠️ Risk Warning
People should beware of thunderstorms, gusty winds, lightning, isolated heavy rain, short-term flooding in urban areas, and flash floods in foothill areas, as well as the dangers of accumulated daytime heat.

🌊 Water Situation and Disasters

📊 Overall Water Situation
Data from HII and ONWR indicates that many areas of Thailand continue to see increasing accumulated rainfall from the onset of the rainy season. As a result, water levels in many large reservoirs have started to rise, while most major rivers remain at normal levels and there are still no nationwide critical water situations.

⚠️ Areas to Monitor
📍 Bangkok and surrounding provinces — Risk of short-term flooding after heavy rain from evening to nighttime.
📍 Eastern region — Watch for accumulated rainfall, runoff, and flooding in low-lying areas.
📍 Foothill areas in the North and South — Beware of flash floods and short-term landslides.

🚨 Disaster Alerts
The National Disaster Warning Center (NDWC) has not issued any severe nationwide disaster warning. However, the public should closely monitor warnings for heavy rain, flash floods, and strong waves during this period.

😷 PM2.5 and Air Quality Situation

📡 Overall Air Quality
Data from Air4Thai and GISTDA indicates that air quality in most parts of Thailand is at a “good to moderate” level, as rainfall helps reduce PM2.5 accumulation. However, some northern provinces still experience high accumulated dust levels during certain morning periods, especially in basin areas.

🔎 PM2.5 Watch Areas
📍 Chiang Mai
📍 Chiang Rai
📍 Mae Hong Son
📍 Lampang
📍 Phayao

⚠️ Recommendations
People in areas with high dust levels should wear PM2.5 protective masks and avoid prolonged outdoor activities, especially children, the elderly, and those with respiratory diseases.
