In
Bangkok,
August is typified by sustained rainfall, making it one of the wettest months of the year. Torrential showers are widespread, resulting in 219mm (8.62") precipitation, spreading across an extensive 20 days, making it the most rainy month. However, daylight duration begins to recede, mirroring the gradual approach of the dry season. Relative humidity also reaches its highest annual level, adding to the city's overall damp theme. As
September approaches, angkorians await a decline in monsoon intensity.
Temperature
With the arrival of August, Bangkok's average high-temperature registers at a still hot 32.9°C (91.2°F), indicating a subtle variation from the previous month. During the month of August, the temperature generally drops to a low average of 25.5°C (77.9°F).
Heat index
For August, the heat index is appraised at a burning hot 46°C (114.8°F).
Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.
Heat index specifics point out values are for conditions of shade and a slight breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
Humidity
In August, the average relative humidity in Bangkok is 76%.

Note: The maximum daily UV index, 12 in August, converts into the following recommendations:
Implement all key precautions. Warding off sun damage is critical. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Regardless of cloud cover, it's recommended to apply generously and reapply often a sunscreen with an SPF of at least 30, especially after swimming or any outdoor activity. Alert! Sand and water increase UV exposure due to their reflective properties.
