Weather in September
Temperature
The average high-temperature during September is a still tropical 88°F (31.1°C), almost matching the conditions of the preceding month. Octagon experiences a mean temperature of 67.1°F (19.5°C) during September nights.Heat index
The heat index value during September is computed to be a very hot 100.4°F (38°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

In September, the average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.Note: In September, the maximum UV index of 6 suggests this advice:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
