Weather in September
Temperature
The average high-temperature during September is a still hot 88.7°F (31.5°C), almost matching the conditions of the preceding month. In September, Billy Goat Hill's temperature tends to fall to an average low of 68.7°F (20.4°C) during the night.Heat index
The heat index in September is appraised at a blisteringly hot 105.8°F (41°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
