September, the first month of the autumn in Eugene, is still a tropical month, with an average temperature fluctuating between 73°F (22.8°C) and 87.1°F (30.6°C).

Temperature

Eugene, Florida, marks the onset of September with an average high-temperature of a still hot 87.1°F (30.6°C), a subtle shift from August's 89.8°F (32.1°C). September witnesses an average low-temperature hovering around an agreeable 73°F (22.8°C).

Heat index

In September, the heat index is evaluated at a sweltering 102.2°F (39°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
