Weather in July
Temperature
Williamsport experiences its highest temperatures in July, with an average peak of 81.7°F (27.6°C) and a low of 59.2°F (15.1°C).Heat index
In July, the heat index is evaluated at a tropical 87.8°F (31°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Note that heat index values are valued for light wind and location in the shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
