Weather in July
Temperature
July, with its average high-temperature of 87.1°F (30.6°C) and an average low-temperature of 67.5°F (19.7°C), holds the record as the warmest month.Heat index
The heat index value for July is calculated to be a torrid 100.4°F (38°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Remember, however, that not all shade structures offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
