Weather in September
Temperature
September registers an average high-temperature of a moderately hot 85.6°F (29.8°C), slightly varied from August's 90.5°F (32.5°C). In September, Bloomingdale reports a consistent average low-temperature of 70.7°F (21.5°C) during the nights.Heat index
For September, the heat index is computed to be a fiery hot 96.8°F (36°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.One should consider that heat index numbers are for shaded settings and light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
