Weather in September

September, the first month of the autumn in Tallahassee, is still a hot month, with an average temperature varying between 87.3°F (30.7°C) and 70.7°F (21.5°C).

Temperature

In September, the average high-temperature is essentially the same as in August - a still hot 87.3°F (30.7°C). In September, in Tallahassee, the average low-temperature is 70.7°F (21.5°C).

Heat index

In September, the average heat index is computed to be a very hot 102°F (38.9°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Note that heat index values are valued for light wind and location in the shade. 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 'real feel', 'feels like', 'apparent temperature', or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is individual, with diverse people perceiving weather differently for numerous reasons (wind, metabolic differences, clothing), and activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 99.5°F (37.5°C) to 100.9°F (38.3°C), thermal conditions are potentially life-threatening.
