Temperature readings reach their annual highs in July, averaging 88°F (31.1°C) and a minimum average of 66.7°F (19.3°C).Heat index
July's average heat index is calculated to be a sweltering 95°F (35°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
