Weather in September
Temperature
Vaughan's progression into September involves a gentle drop in the average high-temperature, from a fiery hot 95.9°F (35.5°C) in August to a tropical 88°F (31.1°C). The nighttime temperature, during September, averages of 70.3°F (21.3°C).Heat index
For most parts of September, the heat index is calculated to be a very hot 96.8°F (36°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
