Cooling Centers in Philadelphia, Pennsylvania

Finding an open cooling center in Philadelphia

Philadelphia declares official heat health emergencies that open cooling centers and a Heatline; residents can also dial 311 or call 211 for the nearest air-conditioned site.

Emergency cooling centers open during declared heat events; the options below are available year-round. Dedicated emergency cooling centers open only during declared heat events, and their locations and hours can change day to day. The fastest, most reliable way to find one open right now in Philadelphia:

• Call 2-1-1 — free and available 24/7 in about 99% of US communities. The operator connects you to current, local cooling-center information. In some areas you can also dial 1-833-342-5211.
• Text your ZIP code to 211 where available to get nearby options by message.
• Check the official Philadelphia or county website — cities post activated cooling centers during declared heat emergencies.
• Check the National Weather Service HeatRisk map for Philadelphia's current heat danger level.

Free air-conditioned spaces in Philadelphia

These places are reliably air-conditioned and open to everyone, so they're a safe fallback even when no emergency center has been activated:

• Public libraries — the single most reliable cooling option. Free, air-conditioned, and open to all with no purchase required. Most offer WiFi, restrooms, and water fountains, and are ADA accessible.
• Shopping malls — air-conditioned, open long hours, free to walk around.
• Community and senior centers — many are designated cooling sites during heat events.
• Movie theaters — reliably cold (purchase required).
• Museums — many offer free days or hours.

Call ahead to confirm hours — Philadelphia library hours vary by branch and season.

Philadelphia's heat and water situation

Philadelphia does not currently have mandatory water restrictions in effect, but it still pays to cool off efficiently:

• Cool showers are unrestricted. Indoor water use is not limited by outdoor watering rules, so a cool (not cold) shower is the fastest safe way to drop your body temperature.
• Sprinklers count as irrigation. Running through a sprinkler may violate Philadelphia's outdoor watering schedule on non-designated days.
• Kiddie pools may be limited. Filling one uses outdoor water that can be restricted during drought.

For the current rules, fines, and your assigned watering days, see the Philadelphia water restrictions page.

No AC? How to stay cool in Philadelphia

Much of Philadelphia's housing predates central AC, and the urban heat-island effect keeps dense blocks hot well after sunset. Cross-ventilate after dark when cooler air (and any sea breeze) arrives, and watch for grid strain during peak demand.

An estimated 35 million Americans have no home air conditioning. These CDC-aligned steps make a real difference:

• Close blinds and curtains during the day, especially on sun-facing windows.
• Open windows for a cross-breeze only when it's cooler outside than inside — early morning and late evening.
• Run ceiling fans counterclockwise; put box fans in windows at night to pull cool air in.
• Take cool showers and put wet cloths on your wrists, neck, and ankles.
• Stay ahead of thirst — a cup of water each hour, don't wait until you feel thirsty.
• Avoid using the oven or stove; grill or eat cold meals instead.
• Ventilate at night, mind the grid. Open opposite windows after dark for a cross-breeze in Philadelphia, and have a cooling-center plan in case heat-driven demand triggers an outage.

Heat safety — warning signs to watch for

Heat exhaustion — heavy sweating, headache, dizziness, nausea, weakness, and cool, clammy skin. Move to a cool place, loosen clothing, sip water, and apply cool cloths. If it doesn't improve within an hour, get medical help.

Heat stroke is a 911 emergency — body temperature of 103°F or higher, hot/red/dry skin, a rapid pulse, confusion, and little or no sweating. Call 911 immediately, move the person to a cool place, and cool them with wet cloths or ice. Do not give fluids to someone who is unconscious.

Highest risk: older adults, young children, outdoor workers, people with chronic conditions, and anyone without AC. Never leave children or pets in a parked car, and check on elderly neighbors during a heat wave.

Staying safe during a heat-wave power outage

Grid strain during heat waves can cause outages right when you need cooling most.

• Call 211 to find a cooling center if your power is out.
• Keep the fridge and freezer closed — food stays safe about 4 hours in an unopened fridge and up to 48 hours in a full freezer.
• Never run a generator indoors or in a garage — carbon monoxide is deadly.
• Charge phones and any medical devices before an expected outage.
• Keep refrigerated medications in an insulated cooler; don't place them directly on ice.
