Temperature

Caledonia experiences an average high-temperature of a still hot 91°F (32.8°C) with the onset of August, subtly varied from July's 91.4°F (33°C). Caledonia's temperature tends to fall to an average low of 71.1°F (21.7°C) during the nights of August.

Heat index

August's heat index is evaluated at an extremely hot 111.2°F (44°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for 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 physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. 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. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
