Temperature

With the onset of September, the average high-temperature registers at a sweltering 37.3°C (99.1°F), subtly different from August's 34.4°C (93.9°F). Throughout September, an average low-temperature of 28.8°C (83.8°F) is expected.

Heat index

For most parts of September, the heat index is appraised at a blisteringly hot 42°C (107.6°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Remember to safeguard yourself. Rapid damage can occur to skin and eyes without protection. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
