Weather in September
Temperature
The shift from August to September is characterized by an average high-temperature of a still hot 31.1°C (88°F), not significantly different from the 31.8°C (89.2°F) of August. Lịch Hội Thượng reports an average low-temperature of 25.2°C (77.4°F) during the nights of September.Heat index
The heat index in September is estimated at an extremely hot 41°C (105.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
