Runner Jake Stein anticipated the temperatures and was out early for his run along the Delaware River.
"Outside of this, I'm staying indoors all day," remarked Stein.
He wasn't alone.
"I definitely don't run as far or as hard as I usually do," stated Aaron Moskowitz of Northern Liberties. "Just try to moderate it and get it when it's cool and cut it short when I need to."
For a lot of people we spoke to around Race Street Pier, what can really make breathing unpleasant is the air quality.
They look for shade and hopefully a little breeze off the water.
"I try to go a little earlier when it's this thick and icky out. Absolutely. But I see a lot of the same people- and so they are all dialing it earlier," said Lynne Smilow of Society Hill.
In Washington Square, Rachel Krauser was out with her daughter's dog, Moses, before it got too steamy.
"I'm out early today so we can take a nice long walk before it gets hot," said Krauser.
Thomas O'Hara of South Philadelphia has lived in different states and feels the heat here can be particularly nasty.
"It's just so muggy. California is dry. Florida is dry. This is muggy. It's unbearable," said O'Hara.
Philadelphia Health Commissioner Cheryl Bettigole issued a Heat Health Emergency, which is scheduled to end at 8 p.m. Tuesday, in response to the forecast maximum heat index values.
A declaration of a Heat Health Emergency activates the city's emergency heat programs, which include the Philadelphia Corporation for Aging Heatline, cooling centers and home visits by special field teams.
The PCA Heatline at 215-765-9040 will be open between 12 p.m. and 11:59 p.m. on Monday and will run from 8:30 a.m. until 8 p.m. on Tuesday.
"The Health Department declares a Heat Health Emergency when the temperature gets high enough that vulnerable people - especially our elderly neighbors and family members - are at an increased risk of getting sick or dying from the heat," said Bettigole.
People who do not have air conditioning are advised to seek relief from the heat by visiting friends or relatives who have air conditioning. The City will be opening a variety of alternate cooling sites that will be available for use by all Philadelphia residents looking to escape the heat.
