Weather in September
Temperature
In Orlando, entering September brings a subtle temperature decrement, reducing from August's tropical 92.8°F (33.8°C) to a moderately hot 84.4°F (29.1°C). Orlando observes an average nighttime low-temperature of 64.9°F (18.3°C) during the month of September.Heat index
The heat index value during September is evaluated at a tropical 89.6°F (32°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' 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 affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 hold great significance to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
