Weather in September
Temperature
September ushers in an average high-temperature of a still hot 33.9°C (93°F), aligning closely with the preceding month. Nighttime temperatures in September average to a warm 23.1°C (73.6°F).Heat index
During September, the heat index is computed to be a blistering 44°C (111.2°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 are particularly relevant to children. 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
