Weather in September
Temperature
September signifies a gentle decline in Caldwell's average high-temperature, easing from a fiery hot 95.7°F (35.4°C) in August to a hot 88.7°F (31.5°C). Caldwell reports a consistent average low-temperature of 70.5°F (21.4°C) throughout September nights.Heat index
The heat index for September is computed to be a sweltering 102.2°F (39°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 vital to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
