Weather in September
Temperature
A mild drop in Alberta's average high-temperature is observed in September, transitioning from a hot 94.6°F (34.8°C) in August to a still tropical 88.5°F (31.4°C). Throughout the month of September, the nighttime temperature dips to an average of 67.3°F (19.6°C).Heat index
The heat index value for September is appraised at a sweltering 102.2°F (39°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
