Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a hot 87.4°F (30.8°C) in August to a moderately hot 81.9°F (27.7°C). In September, Moons reports a consistent average low-temperature of 62.4°F (16.9°C) during the nights.Heat index
The heat index in September is evaluated at a hot 87.8°F (31°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.

Take care. Persons with lighter skin might suffer burns in less than 30 minutes. The mid-day Sun emits the most powerful UV radiation, so seek shade and minimize exposure. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
