Weather in September
Temperature
Purvis Still, Florida, ushers in September with an average high-temperature of a still hot 88.2°F (31.2°C), showing a close resemblance to the previous month. Throughout the nights in September, Purvis Still experiences an average low-temperature of 70.7°F (21.5°C).Heat index
The heat index value during September is estimated at a blisteringly hot 104°F (40°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
