Temperature

September reports an average high-temperature of a still hot 32.2°C (90°F), slightly varied from August's 33.1°C (91.6°F). Throughout September, an average low-temperature of 23.5°C (74.3°F) is expected.

Heat index

For September, the heat index is evaluated at a life-threatening hot 46°C (114.8°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. 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. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Humidity

The average relative humidity in September is 83%.

Note: A typical high UV index of 7 in September suggests the following recommendations:
Resist extreme sun exposure. Guarding against solar damage is essential. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
