Weather in July
Temperature
Wynona registers the highest average temperatures during the month of July, with peaks of 91.2°F (32.9°C) and lows of 72°F (22.2°C).Heat index
The heat index for July is computed to be a scorching 109.4°F (43°C). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.In the scope of the heat index, its values resonate with shade and light wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
