Weather in July
Temperature
July is the warmest month of the year, registering average temperatures as high as 86.4°F (30.2°C) and as low as 69.3°F (20.7°C).Heat index
July's heat index is computed to be a torrid 96.8°F (36°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Realize that the values for the heat index are set for shaded places and light winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
Humidity
The average relative humidity in July is 72%.Rainfall
In Philadelphia, during July, the rain falls for 14.8 days and regularly aggregates up to 1.54" (39mm) of precipitation. In Philadelphia, Pennsylvania, during the entire year, the rain falls for 127.8 days and collects up to 13.82" (351mm) of precipitation.Snowfall
June through October are months without snowfall.Ocean temperature
In July, the average ocean temperature is 73.9°F (23.3°C).Note: A person's cold intolerance, with sunshine, wind, and air temperature, are essential factors for enjoying swimming in 73.9°F (23.3°C) water. (FYI: The Olympic swimming competition requires a water temperature between 77°F (25°C) and 82.4°F (28°C).)
Daylight

Sunshine
The month with the most sunshine is July, with an average of 10.6h of sunshine.UV index
May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.Note: In July, the maximum UV index of 6 suggests these recommendations:
Guard oneself from overexposure. Defence against sun injury is vital. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
