Weather in September
Temperature
September ushers in a minor alteration in Wallaceburg's climate, with the average high-temperature moving from August's tropical 93.2°F (34°C) to a still hot 86.9°F (30.5°C). Wallaceburg's temperature drops to an average low of 65.7°F (18.7°C) during the nights of September.Heat index
Throughout September, the heat index is computed to be a torrid 98.6°F (37°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun. On your guard! Snow's reflection can almost double the intensity of the Sun's UV radiation.
