Summer is here and so is the first heat wave of the season. For the first time in over a decade, the city’s temperature has cracked 100°F, breaking a heat record that’s been standing since July 2012. According to the National Weather Service, today’s brutal spike marks the start of a dangerous and sustained heat weave expected to last through much of the week.
What’s happening with the weather?
A heat advisory has been issued for the entire Philadelphia region with “feels like” temps soaring well above 100°F thanks to high humidity. The hottest hours are expected between 1 p.m and 6 p.m., but the oppressive heat won’t full break overnight, creating health risks for vulnerable residents.
How rare is this?
This is the first time in 12 years that temperatures in Philly have hit 100+ degrees. The last time we saw this kid of heat was July 18, 2012. Prior to that, you’d have to look back at 1995 and 1999. In other words, this isn’t just hot. It’s historic.
How to stay safe during the heat wave
Important to note, there is a current extreme heat advisory in place until Wednesday evening for our area. There is also a code orange air quality alert.
At these temperatures, heat stroke and exhaustion are possible so it is important to stay cool and safe.
Here are some tips:
- 💧 Hydrate constantly—even if you’re not thirsty
- 🧊 Avoid outdoor activity during peak heat hours
- 🏠 Stay indoors in air-conditioned spaces when possible
- 🚿 Take cool showers or baths to lower body temperature
- 🐾 Check on pets, neighbors, and seniors
- ❄️ Use city cooling centers (open today across all five counties)
