Weather in July
Temperature
The average temperatures reach their apex in July, averaging 85.6°F (29.8°C) at the high end and 68.2°F (20.1°C) at the low end.Heat index
The heat index value during July is appraised at a torrid 98.6°F (37°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Shield from overexposure. Defense against sun-related harm is required. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
