Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a hot 89.8°F (32.1°C) in August to a moderately hot 82.4°F (28°C). Gepp documents a marked decrease from day to night, with an average low of 60.4°F (15.8°C) throughout September.Heat index
The average heat index in September is appraised at a hot 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
