August weather forecast
Bangkok, Thailand

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

August's weather records an average high-temperature of a still hot 32.9°C (91.2°F), showing little deviation from July. In the month of August, the average temperature dips to a warm 25.5°C (77.9°F) during the night.

Heat index

August's average heat index is computed to be a burning hot 46°C (114.8°F). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
Research indicates the heat index considers values in shaded locales and with light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

In Bangkok, the average relative humidity in August is 76%.

UV index

February through September, with an average maximum UV index of 12, are months with the highest UV index in Bangkok. A UV Index of 11, and more, symbolizes an extreme threat to health from unprotected exposure to Sun's UV rays for the average person.
Note: The UV index of 12 during August translates into the following guidance:
Take every vital safeguard, as unprotected skin and eyes may suffer burns rapidly. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat. Use liberally and reapply a broad-spectrum sunscreen with at least SPF 30 every two hours and right after outdoor activities or a swim. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
