Pool Winterization Guide: How to Protect Your Pool from Ice Storms & Freezes

Mississippi Gulf Coast Homeowners (Long Beach, Bay St. Louis, Diamondhead, Pass Christian)

On the Mississippi Gulf Coast, winters are mild with average lows around 44–47°F and freezes rare—but when an ice storm or hard freeze hits (like occasional dips below 32°F), unprotected pools face serious risks: cracked PVC pipes, burst pumps/filters, or liner damage costing thousands in repairs.

At Precision Pool & Patio, we help homeowners in Long Beach, Bay St. Louis, Diamondhead, Pass Christian, and across the Gulf Coast prepare for these events. Unlike northern states, you don’t need full “winter closing”—focus on freeze protection and basic winterization to keep your pool safe and ready for early spring swims.

Follow this ultimate guide for pool winterization Mississippi Gulf Coast style.

1. Adjust Water Level to Handle Expansion & Freeze Pressure

Freezing water expands ~9%, stressing skimmers, tiles, and walls.

• Above-Ground Pools: Lower water 4–6 inches below skimmer to prevent ice pressure.
• In-Ground Pools: Drop below tile line or skimmer throat (use skimmer plugs if needed).
• Pro Tip from Precision Pool & Patio: Never drain completely—water weight prevents liner “floating” or hydrostatic pressure issues from ground freeze in rare cold snaps.

2. Balance & Treat Chemicals for Winter Dormancy

Treat water to stay clear through mild Gulf winters—no heavy algae if balanced.

Key parameters for Mississippi Gulf Coast pools in winter:

Parameter	Ideal Range	Why It Matters During Freezes/Ice Storms
pH	7.2–7.6	Prevents scaling/etching when water sits dormant
Total Alkalinity	80–120 ppm	Buffers pH against rain or melt changes
Calcium Hardness	200–400 ppm	Protects surfaces in hard local water
Free Chlorine	1–3 ppm	Maintains sanitation; add non-chlorine shock if needed

• Shock with non-chlorine or calcium hypochlorite.
• Add long-lasting winter algaecide.
• Pro Tip: Test before any freeze—our Gulf humidity can shift levels fast.

3. Winterize & Insulate Equipment (Most Critical Step)

Pumps, filters, and heaters crack easily in freezes.

• Drain pump, filter, heater: Remove plugs; blow out lines with shop vac to clear trapped water in elbows/plumbing.
• Insulate exposed pipes: Use foam sleeves or heat tape (especially important in salt-air corrosion-prone areas like Bay St. Louis).
• Store removable parts: Move pump motor indoors if possible.
• Activate freeze protection: If your system has auto-freeze sensors/heaters, test them now.

4. Install a Durable Winter Pool Cover

Standard covers fail in ice/snow/wind.

• Safety Covers: Anchor to deck; support ice/snow weight.
• Solid Winter Covers: Block UV (prevents algae); use cover pump for meltwater.
• Air Pillows (Above-Ground): Center pillow absorbs ice expansion inward.
• Pro Tip: Secure tightly—Gulf winds can loosen anchors during storms.

5. Remove & Store Accessories

Prevent wind/ice damage or corrosion.

• Take off ladders, handrails, diving boards.
• Store skimmer baskets, cleaners, fittings indoors.
• Metal parts corrode faster in freezing, treated water.

6. Monitor During & After the Storm

Prep is key, but stay vigilant.

• Check cover anchors after wind/ice.
• Never hammer ice—shockwaves damage liners/shells; let melt naturally.
• Post-thaw: Inspect for cracks; retest water; check for leaks if level dropped.
