There’s no denying that it gets hot in Philadelphia during the summertime.
Urban areas, like Philadelphia, are hotter in the spring and summer when temperatures rise. This can be attributed to something dubbed the “urban heat island effect”.
Cities have less tree canopy cover and vegetation, more paved surfaces, row homes with dark rooftops, and taller building structures that reduce airflow.
Very hot weather can make people sick, even healthy adults. Older adults, those who are pregnant, infants and young children, people experiencing homelessness, and people with pre-existing health conditions are at higher risk. This is even more difficult during the COVID-19 pandemic. Here are a few tips to help you stay cool this summer.
Drink more fluids.
Regardless of your activity level, don’t wait until you’re thirsty to drink. Avoid liquids that contain alcohol or large amounts of sugar–these actually cause you to lose more body fluids. Make sure to bring a water bottle with you when you go outside and keep it filled with cool water.
- Pro Tip: Philly’s tap water meets or exceeds all Federal and State safety regulations, making it safe, affordable, and delicious to drink. Learn more about Philly’s drinking water quality!
Never use a fan with windows closed.
The style of Philadelphia row homes plays a role in heat stress. Brick row homes with black roof-tops absorb heat. The temperature inside a home with closed windows can equal that outside the home in something called a “convection oven” effect. Turning a fan on inside a home that has closed windows only circulates the hot air, causing the oven effect.
If you don’t have air conditioning in your house, make sure to open a window when you turn on a fan.
Wear lightweight, light-colored, loose-fitting clothing.
Seek out fabrics that allow air to flow around your body. Light colored, natural fabrics are also good for masks and face coverings.
Take a cool bath or shower.
Take a cool shower or bath, or move to an air-conditioned place to cool off.
- Remember: Do not use fire hydrants to cool off, they are for fighting fires. According to the Philadelphia Water Department, opening hydrants to cool off decreases water pressure and makes it difficult for firefighters to do their jobs, plus it can damage water mains. The water pressure alone from a hydrant can cause serious injury or even death, especially if there are little kids around.
Wear a wide-brimmed hat and sunglasses, and put on sunscreen.
Seek out shade wherever possible to avoid direct sunlight. If you’re going to be outside for any amount of time, make sure you are protected from the sun’s rays. Even if you are wearing a face mask, you need to apply sunscreen.
Call the Homeless Outreach Hotline if you see someone on the street who needs shelter.
The Office of Homeless Services will dispatch their homeless outreach team to any individual on the street who needs to be transported to a local shelter or who needs other homeless services.
- Tip: save this number in your phone to request outreach anytime, 365 days a year, 24 hours a day. Homeless Outreach Hotline: 215-232-1984.
Limit your outdoor activity to morning and evening hours as much as possible.
Remember, if the temperature has been over 90 degrees for a few days, even morning and evening hours can be overly hot and dangerous times.
NEVER leave children and pets unattended in vehicles under any circumstances.
During warm or hot weather car interiors can reach lethal temperatures. It takes only two minutes for a car to reach unsafe temperatures.

Don’t forget about your pets!
Pets can suffer from heat-related illness too.
Make sure your pet has a ventilated, cool place to lay and plenty of water.
If you have air conditioning, keep them inside with you.
Do not leave your pet outside for extended periods of time.
When outside, ensure shade and cool water.
Keep their paws safe.
Dog and cat paws have foot-pads which can burn on hot surfaces like concrete, metal, pavement, sidewalks and asphalt. Ouch! Remember to try to walk them in shaded areas and pay attention to any signs of discomfort.
Follow ACCT Philly’s extreme weather requirements during a Code Red.
A Code Red is when the National Weather Service extended weather forecast includes at least three consecutive days of 95 degrees or above temperatures with high humidity.
- Remember: Owners can face a $500 fine (and can put their pets in grave danger) if they don’t follow ACCT Philly’s requirements. Make sure to familiarize yourself with ACCT Philly’s extreme weather information.
