Weather in July
Temperature
July temperatures tend to peak at an average high of 91°F (32.8°C) and dip to a low of 72.1°F (22.3°C).Heat index
July's average heat index is estimated at a scorching 109.4°F (43°C). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.Understand that the heat index values take into account shaded locations and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Fend off overexposure. Sun protection is vital. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
