Weather in July

July, the same as June, is a moderately hot summer month in Valley Forge, Pennsylvania, with an average temperature fluctuating between 66.7°F (19.3°C) and 85.1°F (29.5°C).

Temperature

The warmest temperatures occur during July, when averages reach a peak of 85.1°F (29.5°C) and a low of 66.7°F (19.3°C).

Heat index

In July, the heat index is estimated at a sweltering 95°F (35°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
