June 18, 2026 · The Clime Team

Cold waves, characterized by prolonged periods of extremely cold temperatures, can pose significant risks to health and safety. Understanding how to prepare for and respond to these conditions is crucial for residents across the United States.

What Is a Cold Wave?

A cold wave is a rapid and sustained drop in temperature over a 24-hour period, leading to dangerously cold conditions. These events can result in hypothermia, frostbite, and other cold-related illnesses. It's essential to recognize the signs of a cold wave and take appropriate precautions.

How Should I Dress During a Cold Wave?

Proper attire is vital to protect against the cold. Dress in layers to trap heat and allow for adjustments as needed:

Inner Layer: Wear moisture-wicking fabrics like wool, silk, or polypropylene to keep skin dry and retain body heat.
Insulation Layer: Choose materials such as wool, fleece, or down to provide warmth by trapping air close to the body.
Outer Layer: Opt for a tightly woven, water-resistant, and windproof coat to shield against the elements.

Don't forget accessories like hats, scarves, mittens, and insulated boots to protect extremities. Avoid tight clothing that can restrict blood flow and increase the risk of frostbite. (cdc.gov)

How Can I Prepare My Home for a Cold Wave?

Ensuring your home is ready can prevent cold-related issues:

Insulate Pipes: Wrap pipes in insulation or layers of newspapers covered in plastic to prevent freezing. Let a trickle of warm water run from a faucet to keep water moving through your pipes. (mass.gov)
Seal Drafts: Use weatherstripping or caulk to seal gaps around windows and doors to keep cold air out.
Maintain Heating Systems: Have your heating system serviced regularly to ensure it's functioning efficiently.
Stock Emergency Supplies: Keep a supply of non-perishable food, water, medications, and blankets in case of power outages.

What Should I Do During a Cold Wave?

During a cold wave, prioritize safety:

Limit Outdoor Exposure: Stay indoors as much as possible. If you must go out, limit the time spent outside and dress appropriately.
Stay Informed: Monitor local weather updates and heed any advisories or warnings issued by authorities.
Check on Vulnerable Individuals: Ensure that elderly family members, neighbors, and those with medical conditions have adequate heating and supplies.
Avoid Alcohol and Caffeine: These substances can impair the body's ability to regulate temperature and increase the risk of cold-related illnesses. (weather.gov)

How Can I Stay Safe After a Cold Wave?

After a cold wave, continue to exercise caution:

Inspect for Damage: Check for frozen or burst pipes and address any issues promptly.
Clear Walkways: Remove ice and snow from driveways and sidewalks to prevent slips and falls.
Be Cautious of Ice: Even after the cold wave has passed, ice can remain on roads and walkways, posing hazards.
