Weather in July
Temperature
July is the month when Mount Vernon's temperatures reach their peak, with averages of 85.6°F (29.8°C) and lows of 65.1°F (18.4°C).Heat index
July's average heat index is calculated to be a torrid 96.8°F (36°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
