Weather in September
Temperature
September implies a soft temperature shift, with average high-temperatures reducing from August's hot 86.7°F (30.4°C) to a warm 81.1°F (27.3°C). The low-temperature in Fairlane averages to a mild 59.9°F (15.5°C) during the nights of September.Heat index
In September, the heat index is computed to be a tropical 86°F (30°C). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 are largely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
