Weather in July
Temperature
In Addison, temperatures reach their average annual highs in July, measuring 81.9°F (27.7°C) and a minimum average of 66.6°F (19.2°C).Heat index
The heat index value for July is computed to be a tropical 87.8°F (31°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Be aware that heat index ratings are designed for shaded locations and minor 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 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
