Weather in September
Temperature

In September, the average heat index is estimated at a tropical 93.2°F (34°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
