Weather in September
Temperature
September is characterized by a mild reduction in the average high-temperature, from a sweltering 95.5°F (35.3°C) in August to a hot 87.1°F (30.6°C). In Aledo, the September nights cool down to an average low of 69.1°F (20.6°C).Heat index
During September, the heat index is computed to be a fiery hot 95°F (35°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
