Weather in August
Temperature
Potomac Heights experiences a subtle adjustment in high-temperatures to a still tropical 86°F (30°C) with the onset of August, maintaining near parity with July's 88.2°F (31.2°C). Potomac Heights experiences an average low-temperature reading of 66.7°F (19.3°C) throughout August.Heat index
The heat index value during August is estimated at a fiery hot 96.8°F (36°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
