A significant reduction in rain to merely 18mm (0.71"), coupled with a maximum UV index of 7, paints the picture of prolonged sunlight hours and scarce precipitation. Though the warmth of the summer months lingers, gradual changes become evident towards the end of the month.

Temperature

With the onset of September, the average high-temperature registers at a still hot 34.3°C (93.7°F), subtly different from August's 33°C (91.4°F). The nighttime temperature during September displays a significant divergence from daily peaks, averaging at an agreeable 21.1°C (70°F).

Heat index

September's mean heat index is estimated at a life-threatening hot 51°C (123.8°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
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. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Deflect overexposure. Sun protection is a necessity. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
