How often Philadelphia gets cold enough to freeze pipes
In NOAA’s 1991–2020 normals for the nearest weather station, Philadelphia averages 77.3 nights a year at or below 32°F and 15.6 at or below 20°F, the temperature at which pipes in unheated spaces start to freeze. The median first 20°F night is Dec 21, so finish winterizing before then. Compare Philadelphia with 500 other U.S. cities.
Philadelphia's weather and your pipes
Philadelphia's water damage risk is driven by a collision of factors unique to the Mid-Atlantic row home belt: Hurricane Ida (September 2021) dropped 6.4 inches in 6 hours, flooding basements across South Philadelphia, Bridesburg, Port Richmond, and Kensington — areas where the combined sewer system overwhelmed and pushed raw sewage into thousands of row home basements simultaneously. Philadelphia has the largest combined sewer system on the East Coast, serving 60% of the city; a 1-inch rainfall event in a 30-minute window is enough to trigger basement sewer backup in the lowest-elevation neighborhoods. The city's housing stock is among the oldest in the country — 67% of Philadelphia homes were built before 1940 — most are row homes with shared party walls, clay tile sewer laterals, galvanized or lead supply lines, and basement party-wall cracks that allow groundwater infiltration during wet periods. The Schuylkill and Delaware River watersheds create Zone AE flood corridors through Manayunk, Bridesburg, and Eastwick that experience FEMA-documented flooding during nor'easters and tropical remnants tracking up the I-95 corridor.
Before, during and after a freeze in Philadelphia
1. Before it gets cold
Disconnect garden hoses, shut and drain outdoor spigots if you have an inside valve, and walk to your main shut-off so you can find it in the dark.
2. The night of the freeze
Let faucets on exterior walls drip, open the cabinet doors under those sinks, keep the thermostat at 55°F or higher even if you are away, and keep the garage door closed.
3. If a pipe freezes
Leave the faucet open and warm the pipe from the faucet end with a hair dryer or heating pad, never an open flame. If water does not return, look for a split before it thaws.
4. If a pipe bursts
Close the main shut-off, switch off power to wet rooms at the breaker, photograph everything, then get the water out and the structure dried before mold starts in 24 to 48 hours.

Philadelphia freeze questions
Is there a freeze warning in Philadelphia tonight?
Not as of Nov 5, 2:19 AM ET. This page reads the National Weather Service feed for Philadelphia's forecast zone every 30 minutes and changes the moment a freeze, hard freeze or extreme cold alert is issued.
At what temperature do pipes freeze in Philadelphia?
Uninsulated pipes in unheated spaces are at risk once the air around them stays at or below about 20°F for several hours. In Philadelphia, as anywhere, the pipes that freeze first run through exterior walls, crawl spaces, attics and garages. A pipe usually splits while frozen and floods when it thaws.
What should I do if a pipe bursts in Philadelphia?
Shut off the main water valve, open the lowest faucet to drain the lines, turn off power to any wet room at the breaker panel, and photograph the damage. Then get the water out and the walls and floor dried with moisture meters: drywall, insulation and framing left wet for 24 to 48 hours are where mold starts.
Who do I call right now for water damage?
Call (888) 840-6512. The line is answered 24 hours a day, seven days a week, and connects you with an IICRC-certified water damage restoration company that serves your area. A recorded menu picks up first: choose water damage or mold, key in your 5-digit ZIP code, and hold through the short silence while the call is passed to the company.
Describe what you can see — where the water is coming from, how long it has been there, and whether it smells — the more specific you are, the faster the right company is on the line. If the source is a pipe or an appliance, shut the main water valve first. Have four things ready and the call goes quickly: the address, when the water started, what is wet now, and whether you have filed an insurance claim.
