Weather in September
Temperature
Florida City marks the start of September with an average high-temperature of a still hot 88°F (31.1°C), hinting at a slight fluctuation from August's 90.1°F (32.3°C). During September, Florida City perceives a slight decrease in temperature from daytime highs, settling at an average low of 79.7°F (26.5°C).Heat index
September's average heat index is computed to be a sweltering 100.4°F (38°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.Note that heat index values are valued for light wind and location in the shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
