Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a still tropical 88.2°F (31.2°C), from a not significantly different 90.1°F (32.3°C). Sunset Harbor observes an average low-temperature of 72.7°F (22.6°C) during September.Heat index
In September, the heat index is estimated at an extremely hot 105.8°F (41°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild 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 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
