Weather in September
Temperature
September experiences an average high-temperature of a moderately hot 85.1°F (29.5°C), barely different from August's 90.1°F (32.3°C). September nights in Nona cool down to an average low-temperature of 65.8°F (18.8°C).Heat index
For September, the heat index is calculated to be a torrid 95°F (35°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
