Quick answer
Dial 211 and ask which warming centers are open today and tonight. In big cities, 311 also knows. Daytime warming sites are often libraries, recreation centers, and senior or community centers. Overnight sites are usually shelters that relax their entry rules during a cold emergency, often called Code Blue. Many cities start at about 32°F, counting wind chill, but the trigger differs from place to place. Warming centers are free, and most do not ask for ID.
Key facts
- Fastest way to find one: call 211, or 311 in cities that use it. Both can tell you what is open right now.
- Common trigger: about 32°F including wind chill (New York City, Chicago), but some cities use precipitation or lower wind chills too.
- Cost: free. Most sites do not require ID or an intake interview.
- Day vs. night: many daytime centers close around 5 p.m.; ask about overnight options before the doors close.
- If someone is outside: call your city's outreach line or 311. Call 911 if the person is confused, unresponsive, or in danger.
- Heat shut off at home? LIHEAP crisis help must be given within 48 hours, or 18 hours if life is threatened.

What is a warming center?
A warming center is a public indoor space that opens to anyone who needs to get out of the cold. It is not a place to live. It is a place to warm up, rest, charge a phone, use a restroom, and get pointed toward other help. Some have hot drinks or snacks. Most have staff who can call a shelter or an outreach team for you.
Warming centers are run by cities, counties, libraries, park districts, churches, and nonprofits. They come in two broad types:
- Daytime warming sites. These are buildings that already exist, such as libraries, recreation centers, senior centers, and community service centers. During cold weather they let anyone sit inside during normal business hours, without a library card or membership.
- Overnight warming shelters. These open in the evening and stay open until morning during a cold emergency. They may be extra rooms at a regular shelter, a gym with cots, or a church hall. Some only open when the city declares a cold weather emergency.
The phrase people search most, "warming centers near me open now," matters because hours change from day to day. A library that served as a warming site at noon may be closed by 6 p.m. That is why a phone call usually beats a map.
Warming centers, shelters, and Code Blue compared
The words get mixed up, and local news often uses them loosely. This table shows how they usually differ. Your city may use its own terms.
| Type | When it is open | Who it serves | Entry rules |
|---|---|---|---|
| Daytime warming site (library, rec center, community center) | Regular business hours on cold days | Anyone, housed or not | Usually walk in; no ID or sign-up |
| Overnight warming shelter | Evening to morning during a cold emergency | Mostly people without a safe place to sleep | Fewer rules than a regular shelter; may ask for a name |
| Year-round emergency shelter | Every night, often with set check-in times | People experiencing homelessness | Often intake, a bed assignment, or a referral |
| Code Blue, Cold Alert, or cold weather emergency | A status the city declares, not a building | Triggers extra outreach, beds, and open hours | Shelters may waive intake or curfews while it lasts |
A cold weather declaration is the switch. When the city declares one, outreach teams go out more often, shelters let people stay inside during the day, and extra warming sites may open. When it ends, hours return to normal.
How to find warming centers near me
There is no single national list of warming centers that is kept up to date. Openings are decided locally, sometimes the same afternoon. These are the sources that know what is open right now.
Call or text 211
Dial 211 from any phone. It is a free, confidential referral line run by United Way partners and local agencies, and in most places it answers 24 hours a day. Ask: "Which warming centers are open today, and which ones are open overnight?" Give your ZIP code or nearest cross streets. In many states you can also text your ZIP code to 898-211, though texting hours and coverage differ by state. You can also search the local 211 for your area at 211.org.
Check your city or county emergency page
Cities post warming center lists on their emergency management, human services, or homeless services pages, and on their social media accounts. Search your city name plus "warming center" and look for a result that ends in .gov or .us. Many cities also run a text alert service; signing up gets you notices when a Code Blue or cold alert starts.
Call 311 in cities that have it
New York City, Chicago, Washington, DC, and many other cities send people to 311 for warming center hours and for help getting someone indoors. 311 can often connect you to a shelter bed after hours, too.
Walk into a public building during the day
If you cannot make a call, a public library, a city recreation center, a senior center, or a hospital lobby is a reasonable place to start. Staff at these buildings usually know whether a warming site is open nearby. In Chicago, for example, the city says its libraries and park buildings may open as warming areas during evenings, weekends, and holidays in extreme cold.
Tip: before you travel, ask whether the site closes at a set time and where people go after it closes. Many daytime centers shut at 5 p.m., and the overnight site may be across town.
When cities open warming centers
Most cities tie openings to a temperature, a wind chill, or a National Weather Service alert. Wind chill is how cold it feels on bare skin when wind is added. A 35°F day with strong wind can feel like the 20s.
The National Weather Service now uses three main cold products. A Cold Weather Advisory means dangerously cold conditions that are not expected to reach warning level. An Extreme Cold Watch means extremely dangerous cold is possible. An Extreme Cold Warning means it is expected or already happening. These replaced the old wind chill advisories and warnings. The temperatures that trigger each one are set by local weather offices, so they are much lower in Minnesota than in Georgia. You can read the definitions on the National Weather Service cold alerts page.
Many cities open warming centers when the weather service issues one of these alerts, even if their own temperature trigger has not been reached. Southern cities often open them at higher temperatures than northern cities, because homes and people there are less prepared for a hard freeze.
Cold-weather rules in four large cities
These examples show how much the rules differ. Each comes from the city's own website, checked on November 5, 2026. Cities can change their triggers before or during a winter, so call 311 or 211 for the current rules.
| City | What it is called | When it starts | Who to call |
|---|---|---|---|
| New York City | Code Blue | 32°F or lower, including wind chill; "Enhanced Code Blue" for wind chills below -5°F, 3+ inches of snow, ice storms, or sustained 40 mph winds | 311 |
| Philadelphia | Code Blue | Precipitation with temperatures at 32°F or lower, or a wind chill near or below 20°F; Enhanced Code Blue after three nights in a row | Outreach hotline (215) 232-1984 |
| Chicago | Warming areas | 32°F or below | 311 |
| Washington, DC | Cold Alert and Extreme Cold Alert (hypothermia season Nov. 1–Mar. 31) | Cold Alert: 16–32°F with wind chill, or 21–40°F with rain or snow. Extreme Cold Alert: below 15°F, or below 20°F with precipitation | Shelter Hotline (202) 399-7093 or 311 |
New York City
According to NYC 311, during Code Blue the city's drop-in centers and shelters run a full open-door policy, and people can stay at any of them without going through the normal intake process. More than 50 hospitals also keep their doors open. Drop-in centers offer meals, showers, laundry, and clothing.
Philadelphia
The City of Philadelphia says Code Blue brings 24-hour outreach, extra shelter beds, and permission to stay inside emergency housing during the day. Warming centers in recreation centers, Free Library branches, and other sites open during an Enhanced Code Blue. The city says they are free and open to the public.
Chicago
The City of Chicago opens warming areas at its six community service centers from 9 a.m. to 5 p.m., Monday through Friday, when it is 32 degrees or colder. The city says the Garfield Community Service Center at 10 South Kedzie is open around the clock to connect people with shelter, and libraries and park buildings may add evening, weekend, and holiday hours in extreme cold. After hours, 311 can arrange a shelter bed.
Washington, DC
The DC mayor's office announced in November 2025 that the District now issues a "Cold Alert" instead of the old "Hypothermia Alert." Hypothermia shelters run from 7 p.m. to 7 a.m. during the season and stay open 24 hours during an Extreme Cold Alert. The Shelter Hotline gives free rides to shelter.
What to bring and what to expect
Most warming centers are simple: chairs or cots, a restroom, and staff. Supplies depend on donations, so plan to bring what you can.
- Medicine you take every day, in the original bottles if you have them.
- A phone and charger. Outlets are often limited, so a power bank helps.
- Dry socks, a hat, and gloves. Wet clothing pulls heat from the body fast.
- A blanket or sleeping bag if you are going to an overnight site.
- Snacks and water, especially for children or anyone with diabetes.
- Baby supplies such as diapers, formula, and a change of clothes.
- Any ID you have. It is usually not required, but it helps if staff refer you to a shelter or benefits office later.
Expect a few basic rules: no weapons, no alcohol or drugs on site, and respect for other guests. Some overnight sites ask for a first name so staff know who is inside. Daytime sites may close at a set hour even on very cold nights, so ask staff where to go next before they close.
Pets, disabilities, and families with children
Service animals and pets
Under the Americans with Disabilities Act, city and county facilities must generally allow service animals, which are dogs trained to do a task for a person with a disability. Emotional support animals and pets are a different matter. Some warming centers accept pets in crates, some partner with animal shelters to board pets for the night, and many do not take pets at all. Ask when you call 211 or 311. The ADA service animal rules explain what staff may and may not ask.
Mobility, hearing, and medical needs
Public buildings used as warming sites are usually wheelchair accessible, but overnight sites in older churches or gyms may not be. Tell the 211 or 311 operator about a wheelchair, oxygen, a CPAP machine that needs power, or a medical condition. They can steer you to a site that fits or ask outreach to help with transportation.
Families with children
Daytime warming sites like libraries welcome families. For overnight help, families are often sent to a family shelter instead of a general warming site. If you have nowhere safe to sleep, our guide to finding a homeless shelter near you explains family intake lines and coordinated entry.
Help for people sleeping outside
Cold kills people who sleep outdoors, even when the temperature is above freezing, because rain, wind, and exhaustion speed heat loss. If you are outside tonight, call 211, 311, or your city's outreach line and ask for a ride to the nearest warming site or shelter. Many cities will send a van.
If you see someone outside who may need help, you can call for them. Give the time, the exact location, and a short description of the person. New York City says it aims to send an outreach team within one hour of a 311 request. Philadelphia's homeless outreach hotline, (215) 232-1984, takes calls about people outdoors during Code Blue. In DC, call the Shelter Hotline at (202) 399-7093.
Call 911 instead if the person is not responding, seems confused, cannot stand, is lying on the ground in the cold, or is in a dangerous spot such as a roadway or train tracks.
Help is free. Warming centers, 211, 311, and city outreach never charge, and applying for official heating help costs nothing.
If your heat is off or about to be shut off
A warming center can get you through a cold day, but the real fix is getting the heat back on. Several kinds of help exist.
- LIHEAP crisis help. The federal Low Income Home Energy Assistance Program pays heating bills and can restore service. Income limits are set by each state, up to 150% of the federal poverty guideline or 60% of state median income. When a household is in crisis, the state must act within 48 hours, or 18 hours if the situation is life-threatening. Our LIHEAP guide explains how to apply.
- Your utility company. Ask about payment plans, medical certificates that delay shutoffs, and any winter shutoff protections in your state. Rules differ by state, so ask the utility or your state utility commission what applies to you.
- Charities and churches. Salvation Army, Catholic Charities, and local community action agencies often help with one-time heating bills. Our guide to emergency help with utility bills lists where to start.
- Weatherization. For the longer term, the federal Weatherization Assistance Program can seal drafts and repair heating systems for free for eligible households.
The federal government also keeps a short page on help with energy bills that links to state LIHEAP offices.
Signs of hypothermia and frostbite
Hypothermia means the body is losing heat faster than it can make it. It can happen indoors in an unheated home, especially to older adults and babies. The CDC lists these warning signs:
- Adults: shivering, exhaustion or feeling very tired, confusion, fumbling hands, memory loss, slurred speech, and drowsiness.
- Babies: bright red, cold skin and very low energy.
If a person's temperature is below 95°F, the CDC says to get medical help right away. While you wait, move them somewhere warm, take off wet clothing, and warm the center of the body first. Give warm, non-alcoholic drinks only if the person is awake and alert.
Frostbite often starts with redness or pain in the skin. Then the skin may turn white or grayish-yellow, feel unusually firm or waxy, and go numb. Fingers, toes, ears, nose, and cheeks are most at risk. Do not rub frostbitten skin, and do not warm it with a heater, heating pad, or fireplace, because numb skin burns easily. Warm water that feels warm, not hot, to an unaffected hand is safer. Get medical care.
Space heaters, generators, and carbon monoxide
When people lose heat, they sometimes reach for whatever is at hand. Some of those choices cause fires or carbon monoxide poisoning, which has no smell or color.
- Never heat a home with an oven or gas stove. The U.S. Fire Administration warns against it.
- Keep space heaters 3 feet from anything that can burn, such as bedding, curtains, and furniture, and turn them off when you leave the room or go to sleep.
- Run generators outside only, at least 20 feet from the house, with the exhaust pointed away. The Consumer Product Safety Commission says never to run one in a home, garage, basement, crawlspace, or shed, even with a door open.
- Install CO alarms on every level and outside each sleeping area, and test them monthly. A battery-powered or battery-backup alarm still works when the power is out.
- Do not use grills, camp stoves, or kerosene heaters indoors unless the device is made and labeled for indoor use.
- Use flashlights, not candles, during outages when you can.
If a CO alarm sounds, or several people in the home feel dizzy, sick to the stomach, or headachy at once, get everyone outside to fresh air and call 911. Then go to a warming center or a friend's home instead of going back in.
Checking on neighbors during a cold snap
Older adults living alone, people with disabilities, and families with newborns are at the highest risk in a cold snap, especially if their heat or power fails. A short check-in can prevent a medical emergency.
- Call or knock once a day while the cold lasts, and more often if the power is out.
- Ask simple questions: Is your heat working? Is it warm inside? Do you have food, water, and your medicine?
- Look for warning signs such as confusion, slurred speech, or a home that feels as cold as outdoors.
- Offer a ride to a warming center, or help them call 211 or 311.
- Ask for a wellness check through 311 or the police non-emergency number if they do not answer and you are worried. Call 911 in an emergency.
Pipes can freeze in a cold, empty home, too. If a neighbor is going to a warming center or to family, a dripping faucet and open cabinet doors under sinks can help keep water moving.

Frequently asked questions
How do I find warming centers near me open now?
Call 211 and ask which warming centers are open now and overnight, or call 311 in cities that have it. You can also check your city or county emergency management page or ask staff at a public library or recreation center.
What is a warming center?
A warming center is a free public indoor space that opens during dangerous cold so anyone can warm up, rest, and get connected to shelter or other help. Daytime sites are often libraries and recreation centers; overnight sites are usually shelters that relax their normal rules.
Do I need ID to use a warming center?
Usually not. Warming centers are meant for anyone who needs to get out of the cold. In New York City, for example, people can stay at shelters and drop-in centers during Code Blue without the normal intake process.
What temperature do warming centers open?
It depends on the city. New York City and Chicago use 32 degrees or lower; Philadelphia uses precipitation at 32 degrees or a wind chill near or below 20 degrees; and many cities also open when the National Weather Service issues a cold alert.
Are there overnight warming centers for homeless people?
Yes, in many areas. During a Code Blue or cold alert, cities add overnight beds and let people stay in shelters during the day. Call 211, 311, or your city's outreach hotline to find one and ask about a ride.
