Weather in July
Temperature
July is the month when Penn sees the highest average temperatures, with a high of 82.6°F (28.1°C) and a low of 61.2°F (16.2°C).Heat index
The heat index in July is estimated at a tropical 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
