Weather in July
Temperature
July registers as the month with the highest average temperatures, reaching 85.5°F (29.7°C) at its peak and 62.1°F (16.7°C) at the lowest.Heat index
The heat index value for July is estimated at a fiery hot 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. 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 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

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. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
