Weather in July
Temperature
In Poolesville, the month of July registers the highest temperatures, averaging 86.7°F (30.4°C) at the peak and 66.7°F (19.3°C) at the lowest.Heat index
In July, the average heat index is evaluated at a very hot 98.6°F (37°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
