Weather in August

During August, the heat index is estimated at a blistering 107.6°F (42°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. 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 particularly meaningful for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. 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 the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
