Weather in July
Temperature
July, characterized by an average high temperature of 88°F (31.1°C) and a low temperature of 68.5°F (20.3°C), is generally the warmest month.Heat index
The heat index for July is evaluated at a blisteringly hot 104°F (40°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
