Weather in September

September in Tallahassee ushers in a respite from the relentless summer heat, as temperatures start to recede. The city witnesses a decrease in rainfall, with a total of 3.62" (92mm) spread across approximately 20 days. Despite the decrease in temperature to a high of 87.3°F (30.7°C), the days remain fairly warm, offering a comforting balance to the residents. September gradually transitions the weather into the milder and more enjoyable autumn season. This month serves as a period of transformation, where the summer's energetic vibes start to wind down, paving the way for the tranquil calm of fall.

Temperature

The transition into September marks the average high-temperature at a still tropical 87.3°F (30.7°C), differing minimally from August's 90.9°F (32.7°C). Tallahassee experiences a steady low-temperature of 70.7°F (21.5°C) throughout September.

Heat index

September's heat index is estimated at a sweltering 102.2°F (39°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
