Weather in September
Temperature
The start of September signals a gentle decrease in the average high-temperature, transitioning from a torrid 96.1°F (35.6°C) in August to a tropical 87.8°F (31°C). During the month of September, an average low-temperature of 70.5°F (21.4°C) is recorded in Highland Park.Heat index
Throughout September, the heat index is evaluated at a very hot 95°F (35°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
