Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from 94.1°F (34.5°C) in August to a still tropical 88.3°F (31.3°C). Throughout the month of September, Simsboro witnesses an average low-temperature of 66.9°F (19.4°C).Heat index
For most parts of September, the heat index is estimated at a very hot 102.2°F (39°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
