Atlanta is known for hot, humid summers and mild winters—but when an Atlanta weather freeze hits, it can be disruptive and even dangerous if you are not prepared. Because hard freezes are less common here than in colder cities, many homes, pipes, and daily routines in metro Atlanta are not fully winterized, which makes planning ahead especially important.
This guide focuses on what an Atlanta freeze really looks like, how it affects daily life, and what you can do before, during, and after a hard freeze in the city.

Key local contacts:
During extended freezes, be prepared for short-term outages and limited heat.
| Topic | What Freezing Means in Atlanta | What You Should Do |
|---|---|---|
| Roads & Driving | Patchy black ice, icy bridges, major delays | Avoid non-essential travel; drive slowly if needed. |
| Home Plumbing | Pipes in crawl spaces, exterior walls may freeze | Insulate, drip faucets, open cabinets. |
| Power & Heat | Higher risk of outages during extreme cold or ice | Have backup light, blankets, and a plan. |
| People & Pets | Hypothermia/frostbite risk for unsheltered people, pets | Limit time outside; bring pets indoors. |
| Plants & Landscaping | Tender plants can be damaged or killed | Cover or bring sensitive plants inside. |
Because many Atlanta homes were not built with frequent freezes in mind, pipes are a major concern when temps drop below 28°F.
Before a freeze:
Insulate exposed pipes
Focus on:
Disconnect garden hoses
A connected hose can trap water and cause the faucet or pipe to burst.
Locate your main water shutoff valve
In Atlanta homes, this is typically:
During a hard freeze:
Let indoor faucets drip slightly
Especially:
Open cabinet doors under sinks
This lets warm air circulate around pipes, particularly in kitchens and bathrooms along outer walls.
Keep your thermostat set consistently
Avoid turning heat way down at night, even if you prefer it cooler.
If you suspect a burst pipe (sudden loss of water pressure, visible leaks, water on floors or walls), shut off the main water valve and contact a plumber. For larger water main breaks in the street, report to Atlanta Watershed Management at 404-658-6500.

Even though winters are usually mild, pets should not be left outside in freezing weather.
Atlanta’s plant life is often chosen for a mild climate, which makes sudden freezes especially damaging.
Common actions before a freeze:
Well-established trees and shrubs usually survive, but tropical or semi-tropical plants (common around intown Atlanta yards) can suffer leaf burn or dieback after hard freezes.
Many Atlanta drivers are not used to winterizing vehicles, but a few simple steps help during cold snaps:
