Weather in August
Temperature
August, characterized by an average high temperature of 91°F (32.8°C) and a low temperature of 78.3°F (25.7°C), is generally the warmest month.Heat index
August's average heat index is computed to be a blazing hot 113°F (45°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.In terms of the heat index, values are set with light wind and shade conditions in mind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
