The onset of September brings a small shift in high-temperatures, falling from 94.6°F (34.8°C) in August to a still tropical 88.7°F (31.5°C). A marked difference from the daytime temperatures, Uncertain's nighttime temperature falls to an average low of 67.1°F (19.5°C) in September.

Heat index

The heat index value for September is evaluated at a very hot 102.2°F (39°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
