Should you clean your pool in winter?

When the weather cools down and the bathers are packed away, it’s easy to forget all about the pool. But ignoring it over winter can cause more headaches than you bargained for once summer rolls around. Here’s how a little maintenance in winter can save you time, money and possibly a few headaches later.

Algae don't take holidays

Just because you’re not swimming doesn’t mean your pool has stopped being a living, breathing body of water. Algae love nothing more than still water and a bit of neglect. If your pool isn’t circulating or chemically balanced, you could be greeted with a slimy green surprise when the weather warms up and the pool cover comes off.

Leaves and debris don’t disappear on their own

Even with a pool cover, leaves have a way of sneaking into your pool. Left to rot, they can stain the surface, clog your filters and upset the chemical balance of the water. Giving your pool a quick scooping once a week and checking the skimmer basket is a simple way to keep things tidy and ticking over.

Winter is prime time for preventative care

Winter is actually a great time to stay on top of maintenance tasks. Because your pool’s not in use, it’s easier to focus on the essentials – like checking the filters, balancing the pH and keeping the pump running smoothly. Even running the system for just a couple of hours a day can help keep everything circulating and prevent stagnation.

A clean, well-maintained pool over winter means fewer repairs, less chemical shock treatment and a lot less scrubbing when summer rolls around.

It saves you money long-term

It might feel like you’re spending time and money on something you’re not using, but winter maintenance is more cost-effective in the long run. Fixing up a neglected pool – green water, broken pump, stains – is far pricier than just keeping it clean and chemically balanced in the first place.

So, what should winter pool care look like?

  • Check and balance your water chemistry – every few weeks is fine
  • Remove debris regularly – especially after storms or windy days
  • Run your filter and pump – even just a few hours a day helps
  • Keep your pool covered – it reduces evaporation, debris and chemical use
  • Inspect equipment – clean filters, and check pumps and skimmers are all working well
