Weather in July
Temperature
Mount Vernon's July weather, with an average high temperature of 91.9°F (33.3°C) and an average low temperature of 74.8°F (23.8°C), tends to be the warmest of the year.Heat index
July's mean heat index is evaluated at a life-threatening hot 116.6°F (47°C). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.Heat index determinations are made taking into account the shade and light air movements. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
