July brings the highest temperatures, with an average high of 90.5°F (32.5°C) and an average low of 74.1°F (23.4°C).Heat index
For most parts of July, the heat index is evaluated at a blisteringly hot 111.2°F (44°C). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate 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. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
