Weather in August
Temperature
The month of August sees the highest average temperatures, reaching 94.8°F (34.9°C) at the peak and 73.2°F (22.9°C) at the low.Heat index
During August, the heat index is estimated at a burning hot 123.8°F (51°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
