Will My Pipes Freeze Tonight? Pueblo Pipe Freeze Risk Tool
Pueblo winters get cold enough to freeze and burst unprotected pipes. The city averages January lows in the teens, with periodic nights below zero. At those temperatures, uninsulated pipes in unheated spaces, on exterior walls, or outdoors can freeze in 2 to 6 hours. A frozen pipe that bursts can discharge hundreds of gallons before it is discovered. This tool estimates tonight's freeze risk and tells you how long you have to act.
The tool attempts to pull tonight's forecast low for Pueblo (lat 38.2544, lon -104.6091) from Open-Meteo's free weather API. If the fetch does not work, enter the temperature manually. If a pipe already froze or burst, skip this tool and follow the burst pipe steps, then call (303) 552-3896.

Prevention Steps for Tonight
This tool is most relevant from November through March for Pueblo County and surrounding mountain communities (Colorado City, Beulah, Rye) which run 10 to 15 degrees colder than city elevations.
Frequently Asked Questions
Water inside a pipe begins to freeze when the pipe wall reaches 32 degrees Fahrenheit. Because the pipe temperature lags the air temperature, air must typically stay below 32 degrees for several sustained hours before an interior pipe freezes. Pipes in unheated spaces (garages, crawl spaces, attics) and outdoor pipes freeze faster because there is no insulating buffer. Pueblo averages January lows in the teens; the surrounding foothills communities (Beulah at 6,200 to 7,500 feet, Rye at 6,200 feet, Colorado City at 5,600 to 6,000 feet) run 10 to 15 degrees colder. See our guide to checking for hidden freeze damage.
At 20 to 27 degrees Fahrenheit, uninsulated pipes in exposed locations typically begin to freeze after 6 to 12 hours. Below 20 degrees, exposed uninsulated pipes can freeze in 2 to 4 hours. Insulated pipes in heated interior walls take much longer and may not freeze unless the home is unheated. Letting a faucet drip keeps water moving and extends the safe window, as moving water freezes more slowly than still water. A pipe repair call for a freeze-cracked line is typically a same-day service.
Wind accelerates heat loss from exposed pipe surfaces, reducing the time to freeze by 30 to 50 percent for outdoor pipes or pipes in drafty, unheated spaces. Wind chill does not lower the pipe temperature below the air temperature itself, but it dramatically speeds cooling for any surface exposed to moving air. Interior insulated pipes are largely unaffected by wind. This tool increases the risk level when wind exceeds 10 mph for exposed or unheated pipe locations.
