Weather in August
Temperature
The warmest time of the year is August, with temperatures averaging a high of 95.7°F (35.4°C) and a low of 75.7°F (24.3°C).Heat index
The heat index in August is calculated to be a burning hot 113°F (45°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
