September weather forecast
Kim Bôi, Vietnam

The first month of the autumn, September, is still a tropical month in Kim Bôi, Vietnam, with an average temperature fluctuating between 31.7°C (89.1°F) and 24.2°C (75.6°F).

Temperature

The unfolding of September shows an average high-temperature of a still tropical 31.7°C (89.1°F), indicating a slight variance from August's 33.1°C (91.6°F). During the month of September, the temperature generally drops to a low average of 24.2°C (75.6°F).

Heat index

For September, the heat index is evaluated at a blisteringly hot 43°C (109.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Humidity

August and September, with an average relative humidity of 80%, are the most humid months.

Rainfall

In September, the rain falls for 18.5 days. Throughout September, 73mm (2.87") of precipitation is accumulated. In Kim Bôi, during the entire year, the rain falls for 181.2 days and collects up to 595mm (23.43") of precipitation.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the average person.
Note: An average maximum UV index of 7 in September leads to these recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Enhance your sun protection with tightly woven, yet airy clothing.
