Weather in September
Temperature
September is characterized by a mild reduction in the average high-temperature, from a hot 87.1°F (30.6°C) in August to a warm 81.5°F (27.5°C). Nighttime temperature lowers to an average of 61.9°F (16.6°C) in September.Heat index
In September, the average heat index is calculated to be a tropical 86°F (30°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.For clarity, heat index numbers account for light winds and areas under shade. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
