Weather in September
Temperature
September is the warmest month, with the temperature often reaching an average high of 28.6°C (83.5°F) and an average low of 19.6°C (67.3°F).Heat index
September's mean heat index is evaluated at a sweltering 35°C (95°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

The months with the highest UV index are March through November, with an average maximum UV index of 6. A UV Index of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for average individuals.Note: The UV index of 6 during September leads to these advisories:
Prevent overexposure. Protection from the sun's harmful effects is needed. 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. Experience reduced UV exposure by about half when donning a wide-brim hat.
