Weather in September
Temperature
September's onset introduces a mild reduction in the average high-temperature, from a tropical 92.7°F (33.7°C) in August to a warm 84.6°F (29.2°C). The mean low-temperature during September nights is a comfortable 65.1°F (18.4°C).Heat index
The heat index value for September is computed to be a hot 89.6°F (32°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
