Weather in August
Temperature
Temperatures reach their maximum during June through August, recording an average high-temperature of 91.9°F (33.3°C).Heat index
In August, the heat index is estimated at a fiery hot 96.8°F (36°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
