Temperature

The advent of September sees the average high-temperature at a still hot 31.7°C (89.1°F), subtly shifted from August's 33.1°C (91.6°F). September sees the temperature falling to a mean low of 24.2°C (75.6°F).

Heat index

The heat index for September is evaluated at a blisteringly hot 43°C (109.4°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

August and September, with an average relative humidity of 80%, are the most humid months.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
