How to Look After Your Pool in Winter

Winter is coming, but that doesn’t mean you should neglect your pool. Proper maintenance during the colder months ensures your pool stays in top condition, so you’re ready to jump in when summer rolls around. Here’s a straightforward guide to help you keep your pool in pristine condition this winter.

Why Winter Maintenance Matters

Even though you’re not using your pool, it’s still exposed to the elements. Leaves, dirt and debris can accumulate, and without proper care, your pool can become a breeding ground for algae and bacteria. Regular maintenance prevents these issues and prolongs the life of your pool equipment.

Steps to Maintain Your Pool in Winter

1. Clean Your Pool Regularly

Even in winter, debris can find its way into your pool. Skim the surface weekly to remove leaves and other debris. Vacuum the bottom of the pool to ensure there’s no dirt build-up.

2. Balance the Water Chemistry

Maintaining proper chemical levels is crucial, even during the off-season. Test your pool water every fortnight and adjust the pH, alkalinity and chlorine levels as needed. Balanced water chemistry prevents algae growth and protects your pool’s surface and equipment.

3. Lower the Water Level

Reduce the water level to just below the skimmer. This helps prevent damage from freezing temperatures, which, although rare in Australia, can still occur in some regions.

4. Use a Pool Cover

Covering your pool reduces the amount of debris that can enter the water. It also helps maintain the chemical balance by reducing the amount of sunlight that reaches the water, preventing algae growth. Make sure the cover is secure and in good condition.

5. Run the Pump

Run your pool pump for a few hours each day. This keeps the water circulating, preventing it from becoming stagnant and helping distribute chemicals evenly.

6. Inspect Your Pool Equipment

Check your pool equipment regularly for any signs of wear or damage. Ensure the filters, pumps, and heaters are functioning properly. Address any issues promptly to avoid costly repairs down the line.

7. Shock the Pool

Consider shocking your pool once or twice during winter. This involves adding a high dose of chlorine to kill any bacteria or algae. Always follow the manufacturer’s instructions when shocking your pool.

8. Keep an Eye on the Weather

Unseasonal weather can affect your pool. Be prepared to adjust your maintenance routine as needed. For instance, after a heavy storm, you might need to clean the pool and balance the water chemistry more frequently.


Winter pool maintenance might seem like a chore, but it’s essential for keeping your pool in great shape. By following these steps, you’ll ensure your pool is ready for use when the warmer weather returns. Remember, a little effort now saves you from bigger problems later.
