Weather in July
Temperature
Mont Vernon's warmest temperatures are experienced in July, with average high temperatures of 81.5°F (27.5°C) and lows of 61°F (16.1°C).Heat index
For July, the heat index is calculated to be a hot 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant 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.
