Weather in August
Temperature
During the warmest month, August, temperatures average a high of 94.6°F (34.8°C) and a low of 75.7°F (24.3°C).Heat index
For August, the heat index is calculated to be a blazing hot 122°F (50°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. 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.
