Weather in September
Temperature
The shift into September reveals an average high-temperature of a still hot 88°F (31.1°C), closely mirroring August's climate. Throughout September in Nicholson, a steady low-temperature average of 71.1°F (21.7°C) is noted.Heat index
The heat index value during September is appraised at a blisteringly hot 104°F (40°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.In reference to the heat index, it's for places in shade and with a slight wind. 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 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Note this! The Sun's UV radiation can nearly be doubled by the reflection off snow.
