Weather in July
Temperature
July is the month that records the highest temperatures, with averages ranging from a high of 91.9°F (33.3°C) to a low of 73.2°F (22.9°C).Heat index
July's heat index is appraised at a burning hot 118.4°F (48°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.Always consider that heat index estimations are for light winds and places in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Inhibit overexposure. Warding off sun damage is of utmost importance. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
