Weather in September
Temperature
September's onset introduces a mild reduction in the average high-temperature, from a tropical 93.6°F (34.2°C) in August to a still hot 86.2°F (30.1°C). During September, Haymond records a consistent average nighttime temperature of 69.4°F (20.8°C).Heat index
The heat index value during September is appraised at a hot 89.6°F (32°C). Ongoing activity coupled with exposure often results in weariness and could induce 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', blends air temperature and moisture content to represent the felt temperature to humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
