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 arrival registers an average high-temperature of a still tropical 32.9°C (91.2°F), closely aligning with the temperature of the previous month. The average temperature during August nights dips to a moderately hot 25.5°C (77.9°F).

Heat index

In August, the average heat index is evaluated at a burning hot 46°C (114.8°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

The average relative humidity in August is 76%.

Rainfall

In August, the rain falls for 20 days. Throughout August, 219mm (8.62") of precipitation is accumulated. In Bangkok, during the entire year, the rain falls for 128 days and collects up to 1648mm (64.88") of precipitation.

Sunshine

August and September, with an average of 5.2h of sunshine, are months with the least sunshine.

UV index

February through September, with an average maximum UV index of 12, are months with the highest UV index. A UV Index estimate of 11, and higher, represents an ultimate health vulnerability from unsafe exposure to UV radiation for the average person.
Note: In August, the UV index of 12 transforms into the following advice:
Employ every precaution of importance, unprotected skin and eyes could burn within moments. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Broad-spectrum sunscreen with an SPF of 30 or above should be applied generously and reapplied every two hours and right after any outdoor activity or swim. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
