Weather in September
Temperature
The advent of September reveals an average high-temperature of a still tropical 88.2°F (31.2°C), showing minimal difference from the prior month. During September, the temperature is averaged to a low of 71.6°F (22°C) at night.Heat index
The average heat index in September is computed to be a scorching 104°F (40°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
