Weather in August
Temperature
August is the warmest month, with an average high-temperature of 91.6°F (33.1°C) and an average low-temperature of 72.3°F (22.4°C).Heat index
The heat index in August is calculated to be a burning hot 114.8°F (46°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
