Weather in September
Temperature
The arrival of September is marked by a minor reduction in average high-temperature, sliding from a sweltering 95.9°F (35.5°C) in August to a hot 90.3°F (32.4°C). Throughout September, the average low-temperature dips to a warm 76.3°F (24.6°C).Heat index
The heat index value for September is appraised at a blistering 107.6°F (42°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. 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. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
