Weather in September
Temperature
The shift from August to September includes a small decrease in the average high-temperature, from a sweltering 95°F (35°C) to a hot 88.9°F (31.6°C). September sees the temperature falling to a mean low of 67.6°F (19.8°C).Heat index
The average heat index in September is calculated to be a blistering 104°F (40°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Consider this! The reflection from snow can almost double the intensity of the Sun's UV radiation.
