Weather in September
Temperature
The start of September comes with a small reduction in the average high-temperature, subtly receding from a sweltering 96.6°F (35.9°C) in August to a hot 88.7°F (31.5°C). In the month of September, an average of 71.6°F (22°C) marks the low-temperature.Heat index
The heat index value during September is computed to be a fiery hot 100.4°F (38°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
