Weather in July
Temperature
July is the warmest month, with an average high-temperature of 90.5°F (32.5°C) and an average low-temperature of 73.2°F (22.9°C).Heat index
The average heat index in July is appraised at an extremely hot 111.2°F (44°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
