Weather in September
Temperature
The shift into September records an average high-temperature of a still tropical 86°F (30°C), subtly varied from August's 91°F (32.8°C). September witnesses an average low-temperature hovering around a refreshing 65.7°F (18.7°C).Heat index
In September, the heat index is computed to be a sweltering 95°F (35°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
