Weather in September
Temperature
September sees a slight reduction in average high-temperature, with a shift from a hot 94.6°F (34.8°C) in August to a still tropical 88.5°F (31.4°C). Alberta reports a consistent average low-temperature of 67.3°F (19.6°C) throughout September nights.Heat index
For most parts of September, the heat index is estimated at a fiery hot 102.2°F (39°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Take precautions - Protection against sun damage is advised. When the Sun's UV radiation is most intense during midday, it's best to find shade and limit exposure. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
