Weather in September
Temperature
The advent of September presents an average high-temperature of a very hot 35°C (95°F), maintaining a close correlation with the preceding month. The nighttime temperature, during September, averages of 24.9°C (76.8°F).Heat index
The average heat index in September is estimated at a blazing hot 45°C (113°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.The heat index's values are generally associated with conditions in shade and light breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Ensure you're always protected. Unprotected skin can get damaged in moments. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
