Weather in August

With average high temperatures of 96.4°F (35.8°C) and lows of 77.2°F (25.1°C), August is the warmest month.Heat index
The heat index value during August is estimated at a blistering 111.2°F (44°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. 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 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
