Weather in September
Temperature
The arrival of September brings an average high-temperature of a still hot 88.5°F (31.4°C), nearly identical to August's 91.4°F (33°C). September is noted for a mean low-temperature of 73.8°F (23.2°C).Heat index
The heat index value for September is appraised at a blistering 105.8°F (41°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 highly important 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
