Temperature

September brings the highest temperatures, with an average high of 30.8°C (87.4°F) and an average low of 25.9°C (78.6°F).

Heat index

The average heat index in September is appraised at a sweltering 39°C (102.2°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
