July is the month when Graff experiences its warmest temperatures, averaging a high of 88°F (31.1°C) and a low of 67.5°F (19.7°C).Heat index
For most parts of July, the heat index is calculated to be a very hot 102.2°F (39°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Remember, devices such as parasols or canopies might not provide complete sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
