Weather in September
Temperature
The arrival of September records an average high-temperature of a moderately hot 83.3°F (28.5°C), closely related to the 88.5°F (31.4°C) observed in August. Nighttime temperature lowers to an average of 63.5°F (17.5°C) in September.Heat index
For most parts of September, the heat index is evaluated at a hot 89.6°F (32°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for 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.
