Weather in September
Temperature
September's onset corresponds with a subtle shift in the average high-temperature, slightly moving from a hot 86.7°F (30.4°C) in August to a moderately hot 81.1°F (27.3°C). Throughout September, the temperature tends to fall to a consistent average low of 59.9°F (15.5°C).Heat index

If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers.
