September weather forecast
Hào Nam, Vietnam

September, the first month of the autumn in Hào Nam, is also a hot month, with an average temperature fluctuating between 31.7°C (89.1°F) and 24.2°C (75.6°F).

Temperature

The shift to September signals an average high-temperature of a still hot 31.7°C (89.1°F), subtly varied from August's 33.1°C (91.6°F). An average low-temperature of 24.2°C (75.6°F) is anticipated throughout the nights during September.

Heat index

September's heat index is computed to be a blistering 43°C (109.4°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Ward off overexposure. Defence against solar harm is crucial. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
