Weather in July
Temperature
July is the warmest month, with the temperature often reaching an average high of 86.9°F (30.5°C) and an average low of 67.6°F (19.8°C).Heat index
For July, the heat index is estimated at a sweltering 98.6°F (37°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
