If you’re a pool owner, you’ve probably asked yourself: “Should I take off my pool cover during winter?” The truth is, the answer depends on where you live, the types of pool you have, and your winter pool cover maintenance habits.
In Cape Town, the colder months bring rain, which means your pool water can fill up fast — but the temperatures are milder. In Johannesburg, it’s drier but much colder, so the way you care for your pool will be different.
At Designer Covers, we’ve been helping South Africans protect your pool since 2012 with high-quality, custom-made pool covers — from thermal blankets to solid safety covers — designed to keep your pool water clean, safe, and looking like the pool of your dreams.
Let’s break down how to keep your pool in top condition all winter long.
1. The Big Winter Pool Question
Why do pool owners debate whether to cover your pool in the winter?
- Covers protect your pool from debris, dirt, and algae growth.
- They reduce evaporation, which helps retain heat and keep the water clean.
- On the flip side, if your pool cover is damaged or neglected, it can trap debris in your pool or mess with your pool water balance.
Cape Town vs Johannesburg in a nutshell:
- Cape Town – Wet winters, risk of overflowing water level in the pool.
- Johannesburg – Dry, colder winters, risk of damage to your pool equipment from freezing.
2. Cape Town vs Johannesburg: How Climate Changes Pool Maintenance
Your location affects your maintenance schedule and pool care approach.
Cape Town:
- Rain increases water level — you’ll need to inspect more often.
- More rain means more chance of debris landing on the cover.
- Algae loves damp, mild climates — keep up with algaecide use.
Johannesburg:
- Less rain but more evaporation.
- Colder months can cause damage to the pool pump or filter if not monitored.
- Lower water level can strain your pool equipment.
3. Should You Cover Your Pool or Leave It Open?
Benefits of leaving the pool cover on:
- Keeps your pool clean and reduces debris.
- Saves on pool chemicals and helps maintain your pool longer.
- Helps protect your pool surfaces during winter months.
Risks of removing it too early:
- Algae growth from direct sunlight.
- More maintenance tasks to keep the pool looking good.
- Increased ph of your pool imbalance.
4. Step-by-Step Winter Pool Cover Maintenance Guide
4.1 Inspect Your Pool Cover Weekly
- Look for rips, sagging, or anything related to your pool cover that might cause problems.
- Inspect the cover for debris build-up — use a pool cleaner or skim off leaves.
- Remove standing water to prevent stress on the cover.
4.2 Maintain Correct Pool Water Level
- Check water level in the pool — too high can cause overflow, too low can damage the pool pump.
- In Cape Town, lower the water level before heavy rain.
- In Johannesburg, top up to reduce evaporation effects.
4.3 Keep Pool Equipment in Check
- Inspect the pool pump, filters, and skimmers.
- Lubricate moving parts and check seals to ensure your pool remains leak-free.
5. Pre-Winter Prep: Pool Before Closing Checklist
Before you close your pool for the season:
- Clean the pool with a pool brush — don’t forget walls and floor.
- Balance water chemistry and adjust ph level.
- Shock your pool to kill bacteria.
- Add algaecide to prevent algae growth.
- Pool before closing care will save time and money later.
6. Winter Pool Water Care – Easy Monthly Routine
Even if the pool is not in use:
- Test ph of your pool and chlorine monthly.
- Add pool chemicals only when necessary to save costs.
- Keep an eye on proper water balance to prevent damage to your pool surfaces.

9. Tips for Maintaining Your Winter Pool Cover
Pool cover maintenance tips to prolong its life:
- Keep the cover clean using mild soap and water.

10. Common Winter Pool Problems & How to Fix Them
- Alga under the cover → Check chlorine and use algaecide.
- Cloudy water → Balance ph of your pool and chlorine.
