Weather in September
Temperature
September's arrival registers an average high-temperature of a still hot 86.9°F (30.5°C), closely aligning with the temperature of the previous month. In West Miami, the September nights are characterized by an average low-temperature of 80.6°F (27°C), a minor dip from daytime readings.Heat index
September's average heat index is computed to be a very hot 98.6°F (37°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
