Weather in July
Temperature
In Romeville, the warmest period comes during July and August, when the average high-temperature touches 89.8°F (32.1°C).Heat index
July's heat index is calculated to be an extremely hot 111.2°F (44°C). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Sunshine

The months with the highest UV index are June through August, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.Note: During July, 7 as the daily maximum UV index converts into the following advice:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
