Weather in September
Temperature
The onset of September manifests an average high-temperature of a still hot 86.5°F (30.3°C), demonstrating a minor variation from the preceding month. An average low-temperature of 76.1°F (24.5°C) marks the nights throughout September.Heat index
The heat index value during September is appraised at a fiery hot 98.6°F (37°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
