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

Temperature
The advent of August signifies a minor shift to an average high-temperature of a still tropical 32.9°C (91.2°F), aligning closely with
July. August brings with it a nighttime average temperature of 25.5°C (77.9°F) in Bangkok,
Thailand.
Heat index
August's heat index is calculated to be a blazing hot 46°C (114.8°F).
Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As body temperatures escalate without effective heat release, one might face dehydration threats.

Note: A maximum UV index of 12 in August translates into the following recommendations:
Utilize all necessary safety measures, unprotected skin could suffer burns instantly. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Post an outdoor workout or swimming, a broad-spectrum SPF 30+ sunscreen should be applied generously and frequently. Caution! The Sun's UV intensity grows with reflections off sand and water.
