The arrival of September sees an average high-temperature of a still tropical 31.5°C (88.7°F), hardly diverging from August's 32.4°C (90.3°F). An average low-temperature of 24.1°C (75.4°F) is anticipated throughout the nights during September.

Heat index

For September, the heat index is estimated at a blisteringly hot 43°C (109.4°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
When referencing the heat index, its values are suitable for shady environments and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

UV index

March through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for ordinary individuals.
Note: In September, the maximum UV index of 7 suggests this advice:
Resist overexposure. Safeguarding from solar damage is indispensable. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
