Temperature

The beginning of September records an average high-temperature of a still tropical 30.9°C (87.6°F), almost echoing the conditions of the previous month. Annur, in the month of September, anticipates a consistent average low-temperature of 21.2°C (70.2°F).

Heat index

September's mean heat index is computed to be a sweltering 37°C (98.6°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. 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. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
