Weather in September

With the onset of September, the average high-temperature subtly recedes from August's hot 86.4°F (30.2°C) to a warm 81°F (27.2°C). In September, Pine Harbor Heights records an average nighttime temperature of 59.7°F (15.4°C).Heat index
September's mean heat index is calculated to be a tropical 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Know that the heat index computations account for shaded terrains and slight winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital 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.
