How often Sioux Falls gets cold enough to freeze pipes
In NOAA’s 1991–2020 normals for the nearest weather station, Sioux Falls averages 162.0 nights a year at or below 32°F and 90.4 at or below 20°F, the temperature at which pipes in unheated spaces start to freeze. The median first 20°F night is Nov 4, so finish winterizing before then. Compare Sioux Falls with 500 other U.S. cities.
Sioux Falls's weather and your pipes
Sioux Falls area properties face South Dakota's climate extremes: winter pipe freeze events at temperatures below -20°F (which occur multiple times per winter in most SD communities), spring flooding from James River and Big Sioux River snowmelt, and summer convective storm flash floods. The Black Hills region (Rapid City, Sturgis, Deadwood) faces mountain storm flash flooding risks that are among the fastest-developing in the country. South Dakota's newer construction often uses PEX plumbing that is more freeze-resistant than copper — but PEX fittings in unheated spaces can still fail.
Before, during and after a freeze in Sioux Falls
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.

Sioux Falls freeze questions
Is there a freeze warning in Sioux Falls tonight?
Not as of Nov 5, 12:24 AM ET. This page reads the National Weather Service feed for Sioux Falls'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 Sioux Falls?
Uninsulated pipes in unheated spaces are at risk once the air around them stays at or below about 20°F for several hours. In Sioux Falls, 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 Sioux Falls?
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.
