Weather in September
Temperature
Transitioning from August to September involves a subtle drop in average high-temperatures, descending from a hot 87.4°F (30.8°C) to a warm 81.5°F (27.5°C). In September, Jason Chapel records an average nighttime temperature of 61.7°F (16.5°C).Heat index
The average heat index in September is calculated to be a tropical 86°F (30°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
