Weather in August
Temperature
The transition into August notes an average high-temperature of a still hot 88.5°F (31.4°C), revealing a mild distinction from the 90.5°F (32.5°C) in July. Dekalb's temperature lowers to a mean of 71.1°F (21.7°C) during the nights in August.Heat index
For most parts of August, the heat index is computed to be a blistering 104°F (40°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
