Weather in September

September welcomes an average high-temperature of a still tropical 30.8°C (87.4°F), not much different from the preceding month. Phong lạc sustains an average of approximately a warm 25.9°C (78.6°F) during September nights, with little variation from daytime highs.Heat index
The heat index value for September is computed to be a torrid 39°C (102.2°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 vital to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
