Weather in July
Temperature
The average temperatures reach their apex in July, averaging 90.7°F (32.6°C) at the high end and 73°F (22.8°C) at the low end.Heat index
For July, the heat index is computed to be an extremely hot 109.4°F (43°C). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
