Weather in August
Temperature
The warmest temperatures occur during August, when averages reach a peak of 94.3°F (34.6°C) and a low of 72.7°F (22.6°C).Heat index
The heat index value during August is evaluated at a blazing hot 116.6°F (47°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
