The leaves are starting to drop, the sun is packing up earlier, and that familiar Adelaide autumn chill is rolling in off the Gulf. If you’re a pool owner in South Australia, now’s the time to ask the big question:
Should you cover your pool this winter — or just leave it be?
It’s a question the team at Adelaide Aqua Boys gets asked every single season. And the honest answer? It depends — but in most cases, a pool cover is one of the smartest investments an Adelaide pool owner can make before the cold really sets in.
What’s the Weather Actually Like in Adelaide in Winter?
Adelaide winters are mild compared to the southern states — but don’t let that fool you. Temperatures regularly drop to single digits overnight, and with average July highs sitting around 15°C, your pool water can plummet fast without the sun doing its job. Add in the typical June-to-August rainfall, strong southerly winds, and debris from surrounding gum trees and gardens, and you’ve got a recipe for a very unhappy pool by the time spring rolls around.
If your pool isn’t protected, you’re not just dealing with cold water — you’re fighting algae blooms, chemical imbalance, and debris buildup that can really do your head in come September.
The Case FOR Covering Your Pool This Winter
Here’s why most Adelaide pool owners are better off covering up:
• Cut back on the chemicals you use in your pool. Sunlight burns off chlorine faster than anything. Cover the pool, and you’ll use significantly less sanitiser over winter, keeping those chemical costs well down.
• Cut water evaporation. With Adelaide’s notoriously dry winters and persistent winds, uncovered pools lose a surprising amount of water. A pool cover can reduce evaporation by up to 97%, which is a big win for both your water bill and SA Water restrictions.
• Keep the muck out. Autumn leaves, insects, bird droppings, and garden debris are the enemy of a clean pool. A cover keeps all that rubbish out, meaning far less work for your filter and your pool cleaner throughout winter.
• Keep your water at the right temperature. Even if you’re not swimming through winter, maintaining a more stable water temperature makes it much easier (and cheaper) to heat your pool back up when spring arrives. If you’ve got solar pool heating or a heat pump, a cover works hand-in-hand with your heating system to hold that warmth overnight.
• Security for children and animals. A solid pool cover adds a layer of safety when the pool isn’t being used regularly — especially important during the months when little ones and pets are less supervised around the backyard.
What Type of Pool Cover Is Right for Your Adelaide Pool?
Not all pool covers are created equal. Here is a summary of the primary choices:
1. Solar Pool Covers (Bubble Covers)
The most popular choice for Adelaide homes. These covers use the sun’s energy to heat the water during the day, then trap that warmth overnight. They’re cost-effective, lightweight, and easy to roll on and off. If you’re looking to extend your swim season into late autumn and early spring, a solar cover is a ripper option. The team at Adelaide Aqua Boys can advise on the right thickness and coverage for your specific pool size and shape.
2. Safety Pool Covers
These are solid, lockable covers designed primarily for child and pet safety. They’re more of an investment upfront but provide serious peace of mind over winter when the pool isn’t in regular use. They also do a great job keeping debris out.
3. Leaf and Debris Covers
A more budget-friendly option designed mainly to keep debris out rather than retain heat. If your pool is near big gum trees or in a leafy suburb like Flagstaff Hill, McLaren Vale, or Brighton, a debris cover can save you hours of skimming and cleaning throughout winter.
What If You Don’t Want to Cover Your Pool?
Fair enough — covering isn’t for everyone. Maybe you swim year-round (legend), or you prefer the look of an open pool in your backyard. If you’re going cover-free this winter, here’s what you need to stay on top of:
• Adjust your chemical dosing schedule as temperatures drop and usage decreases
• Check water balance at least fortnightly — pH, alkalinity, and sanitiser levels can shift quickly in cooler weather
• Keep your filter running on a reduced schedule to save on power but maintain circulation
• Book a winter pool service to get ahead of any equipment issues before they become expensive repairs in spring
