Weather in July

Unfolding amidst the summer revelry is July, which stakes its claim as the hottest month in Bethlehem with peaks touching 83.5°F (28.6°C). As temperatures notably amplify, pressure slightly takes a dip, signifying the general stability attached to summer's full bloom. And while rain showers occur, they seldom mar the long and sunny afternoons that the city luxuriates in. Outdoor barbeques, swimming sessions, and park visits become the order of the day, making the summer's prime month a period of relaxation and enjoyment. However, the increased UV index of 6 stresses the need for precautionary measures against sunburn.

Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly important for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
