Weather in September
Temperature
The arrival of September coincides with an average high-temperature of a moderately hot 81.9°F (27.7°C), indicating a minimal shift from August's 86.2°F (30.1°C). Throughout September, an average low-temperature of 63°F (17.2°C) is experienced.Heat index
The heat index for September is estimated at a hot 86°F (30°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Observations indicate that the heat index values are for shady locations with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
