, the first month of the summer, in Bangkok
, is still a tropical month, with average temperature ranging between min 26.1°C (79°F) and max 33.6°C (92.5°F).
In June, the average high-temperature is essentially the same as in May
- a still hot 33.6°C (92.5°F). The average low-temperature, in June, is 26.1°C (79°F).
In June, the average heat index is evaluated at a burning hot 47.4°C (117.3°F). Be wary
: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'feels like', 'real feel', 'felt air temperature', or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors like differences in body mass, height, and shape, wind, clothing, and activity influence one's weather impression. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
In June, the average relative humidity is 74%.
In Bangkok, Thailand
,, during 16 rainfall days, 157.1mm (6.19") of precipitation is typically accumulated. In Bangkok, during the entire year, the rain falls for 128 days and collects up to 1648.2mm (64.89") of precipitation.

Months with the highest UV index in Bangkok are February
, with an average maximum UV index of 12. A UV Index of 11, and more, symbolizes an ultimate health vulnerability from unprotected exposure to the Sun's UV rays for average individuals.Note
: In June, the average maximum UV index of 12 translate into the following recommendations:
Take all required precautions, as unprotected skin and eyes can burn in minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
