Weather in September
Temperature
The arrival of September brings an average high-temperature of a still tropical 87.1°F (30.6°C), closely following the temperature pattern of August. September's nights observe an average temperature of 73°F (22.8°C).Heat index
The heat index in September is computed to be a very hot 102.2°F (39°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
