Philadelphia residents will get a taste of classic summer heat starting Thursday, as temperatures climb toward the mid-80s before surging near 90 degrees by the weekend. Following a brief spell of clouds and sprinkles overnight, a persistent stretch of dry, sunny weather will bring increasingly hot afternoons across the city and surrounding suburbs.
According to the National Weather Service, scattered sprinkles overnight will give way to cloudy skies on Wednesday, with highs around 83°F. Skies will clear on Thursday, pushing temperatures up to 84°F, then up to 85°F on Friday. Humidity levels will remain moderate, but by Saturday and Sunday, expect highs of 87–90°F with mostly sunny skies and light winds, elevating the risk for heat-related stress, especially in urban areas.
Wednesday: Cloudy, slight chance of sprinkles, high near 83°F.
Thursday: Mostly sunny and warmer, high 84°F.
Friday: Sunny, high 85°F, comfortable at night in the low 60s.
Saturday: Full sun, highs soar to 87°F.
Sunday: Mostly sunny, highs pushing 90°F, overnight lows in the 70s.
Hot, sunny conditions are likely to persist into early next week, so limit outdoor activities during peak afternoon hours and stay hydrated. More advisories are possible if the heat intensifies or air quality becomes a concern.
