Weather in August
Temperature
August is the warmest month, with an average high-temperature of 95°F (35°C) and an average low-temperature of 73.6°F (23.1°C).Heat index
The heat index value for August is estimated at a blistering 109.4°F (43°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Always consider that heat index estimations are for light winds and places in the shade. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. 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. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
