Weather in September
Temperature
The arrival of September suggests a slight decrease in the average high-temperature, moving from a hot 94.1°F (34.5°C) in August to a warm 85.3°F (29.6°C). Throughout September, an average low-temperature of 68°F (20°C) is experienced.Heat index
September's mean heat index is calculated to be a tropical 87.8°F (31°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. 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. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
