Georgia winters are mild, but “mild” isn’t “nothing.” Here in zone 8a many pools stay open all winter, and the goal isn’t a full Northern-style shutdown — it’s protecting against the occasional hard freeze while keeping the water healthy. Here’s how to prep a Northeast Georgia pool for the cold months.

First: open or closed?

Because our freezes are short, a lot of local owners keep the pool open year-round and simply guard against freezing. If you won’t use it for months, a partial winterization saves chemicals and wear. Either path works — just commit to one and do it properly.

If you keep the pool open

• Freeze protection is everything. Moving water is much harder to freeze. Set your automation’s freeze-protect feature to run the pump automatically when temperatures drop near freezing; if you don’t have automation, run the pump continuously during a hard freeze.
• Keep the water balanced and chlorinated — cold water needs less chlorine, but it still needs some.
• Keep the level normal and the filter clean so flow stays strong when you need it most.

If you’re closing it for the season

1. Balance the water first (pH, alkalinity, calcium) to protect surfaces over the idle months.
2. Add a winterizing/algaecide treatment and shock.
3. Lower the water below the skimmer (or use skimmer plugs).
4. Blow out and plug the lines, and drain the pump, filter, and heater so no water can freeze inside them — this is the step that prevents cracked equipment.
5. Cover the pool with a secured safety cover.

The mistake that cracks equipment

The costliest winter damage in Georgia isn’t a frozen pool — it’s water left sitting in a pump, filter, or pipe during a hard freeze. Whatever approach you choose, make sure standing water can’t freeze inside the equipment. When in doubt, run the pump.

Spring is easier when winter is done right

A pool that was balanced and protected over winter opens clear and trouble-free. Pair this with our year-round maintenance guide and you’ll spend spring swimming, not recovering.

Freeze protection, in depth

The key fact: moving water is far harder to freeze. Modern automation has a freeze-protect setting that starts the pump automatically when the air nears freezing — set it and forget it. Without automation, run the pump continuously through a hard freeze. Protect exposed plumbing and the equipment pad, and never let water sit still in the pipes or pump when temperatures drop into the 20s.

Saltwater systems in winter

Salt cells stop generating chlorine in cold water (typically below about 50–60°F), so if you keep a salt pool open through winter, you may need to add a little chlorine manually during cold snaps. Keep the cell and water balanced, and follow the same freeze-protection rules as any other pool.

Spring reopening checklist

1. Remove and clean the cover.
2. Top off the water and restart the equipment.
3. Balance the water — alkalinity, then pH, then chlorine and stabilizer.
4. Run the filter continuously for a day or two and brush the surfaces.

Frequently asked questions

Do I need to winterize my pool in Georgia?

Our winters are mild, so many local pools stay open year-round — the main job is protecting against the occasional hard freeze. Full closures are optional.

How do I protect my pool from a freeze?

Keep the water moving — set your automation's freeze-protect feature, or run the pump continuously during a hard freeze. Moving water is much harder to freeze.

What causes the most winter damage?

Water left sitting in a pump, filter, or pipe during a hard freeze. Whatever approach you choose, make sure standing water can't freeze inside the equipment.
