Weather in September
Temperature
September reveals a small adjustment in temperature, transitioning from an average high of a hot 87.4°F (30.8°C) in August to a moderately hot 82°F (27.8°C). An average low-temperature of 65.3°F (18.5°C) is recorded during the nights in September.Heat index
In September, the heat index is estimated at a hot 89.6°F (32°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.Consider that heat index readings are for situations in the shade and light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for 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.
