Weather in September
Temperature
The commencement of September indicates a gentle shift in the average high-temperature, receding from August's very hot 95.5°F (35.3°C) to a tropical 87.6°F (30.9°C). The nights of September in Forreston anticipate an average low-temperature of 70°F (21.1°C).Heat index
For September, the heat index is evaluated at a very hot 96.8°F (36°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
