Weather in September
Temperature
The start of September marks an average high-temperature of a sweltering 35°C (95°F), hardly distinguishable from the conditions in August. An average low-temperature of 24.9°C (76.8°F) is noted during the month of September.Heat index
The average heat index in September is evaluated at a life-threatening hot 45°C (113°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. 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 are primarily vital for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
