Weather in September
Temperature
September witnesses a gentle descent in average high-temperature, descending from August's hot 89.1°F (31.7°C) to a warm 83.3°F (28.5°C). Throughout the nights in September, an average low-temperature of 65.3°F (18.5°C) is noted.Heat index
In September, the heat index is evaluated at a hot 89.6°F (32°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.It is crucial to understand that heat index figures are for shade and gentle 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 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
