Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a very hot 98.2°F (36.8°C) in August to a hot 91°F (32.8°C). During September, Calliham's temperature averages to a warm 74.1°F (23.4°C) at night.Heat index
The heat index value during September is appraised at a blistering 107.6°F (42°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
