The last month of the summer, August
, is another tropical month in Bangkok
, with average temperature fluctuating between 25.5°C (77.9°F) and 32.9°C (91.2°F).
In August, the average high-temperature is relatively the same as in July
- a still hot 32.9°C (91.2°F). The average low-temperature, in August, is 25.5°C (77.9°F).
In August, the average heat index is evaluated at a blazing hot 45.8°C (114.4°F). Beware
: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'felt air temperature', 'real feel', 'feels like', or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect is individual, with diverse people perceiving weather differently for numerous reasons (pregnancy, clothing, wind), and activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
In August, the average relative humidity is 76%.
In August, the rain falls for 20 days. Throughout August, 219.3mm (8.63") of precipitation is accumulated. Throughout the year, in Bangkok, there are 128 rainfall days, and 1648.2mm (64.89") of precipitation is accumulated.
In August, the average sea temperature in Bangkok is 28.9°C (84°F).Note
: For swimming, diving, and other water activities, temperatures between 25°C (77°F) and 29°C (84.2°F) are perceived as very enjoyable and pleasurable for prolonged periods without feeling uncomfortable.
In August, the average length of the day is 12.6h.
Months with the least sunshine are August and September
, with an average of 5.2h of sunshine.
through September, with an average maximum UV index of 12, are months with the highest UV index in Bangkok. A UV Index reading of 11, and higher, represents an ultimate health vulnerability from unprotected exposure to the Sun's UV rays for the average person.Note
: In August, the average maximum UV index of 12 translate into the following recommendations:
Practice all-important precautions. Light skin people may get burned in less than 5 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. 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. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
