Philadelphia, PA – A surge of summer heat is sweeping across Pennsylvania, New Jersey, and Delaware, with temperatures in Philadelphia expected to soar as high as 92°F by Thursday. Residents can expect dry air and low humidity to linger through Tuesday, but warmer, stickier weather will settle in midweek.
According to the National Weather Service in Mount Holly, a drier air mass will dominate through Tuesday, keeping humidity low and skies mostly sunny. By Wednesday, humidity will climb slightly, with afternoon highs reaching 86°F and a few clouds dotting the region. Thursday marks a significant shift, as much warmer and more humid air arrives, pushing daytime highs toward 92°F in Philadelphia, Trenton, and Wilmington.
Travelers heading to the Jersey Shore or Delaware Beaches will encounter a low risk of dangerous rip currents through Thursday, but beachgoers should stay alert for changing conditions. Area schools and commuters should plan for increased heat, especially during afternoon hours. With the oppressive heat building, it’s a good time to check air conditioning, stay hydrated, and limit outdoor activities.
No rain is expected before Thursday night, but the National Weather Service warns that even hotter, more oppressive conditions could develop by Friday. Additional advisories may be issued as the week progresses.
