Weather in August
Temperature
Callahan's weather in August, with an average high-temperature of a still tropical 90.9°F (32.7°C), subtly shifts from July's 91.2°F (32.9°C). Throughout August, an average nighttime temperature of 76.5°F (24.7°C) is experienced.Heat index
The heat index value during August is appraised at a life-threatening hot 113°F (45°C). Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.Heat index data is primarily for areas with shade and subjected to light winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
