Ask five pool owners in Cyprus what they do in winter and you’ll get five different answers. Some cover the pool in November and forget it exists until May. Some keep it running exactly as in summer. Most do something in between — and quite a few do nothing at all, which is how so many pools end up green by Easter.
The honest answer is that in Cyprus, unlike northern Europe, there is no single “correct” approach. Our winters are mild enough that a full closure isn’t necessary — but our pools aren’t maintenance-free in January either. Here’s how to decide what’s right for your pool.
Why the usual advice doesn’t apply here
Most pool-closing guides you’ll find online are written for the UK, Germany, or the northern US, where the question is really about frost. There, you close the pool because freezing water will crack pipes, tiles, and pump housings. That’s why “winterising” traditionally means draining the lines, adding antifreeze, and lowering the water level.
In coastal Cyprus, hard frost is essentially a non-issue. Limassol, Paphos, and Larnaca rarely drop below 5–8°C even on cold nights, and pool water — a large thermal mass — stays well above freezing all winter. Only pools up in the Troodos foothills need to think seriously about frost protection.
So in Cyprus the question isn’t “will my pool freeze?” It’s “what’s the cheapest way to get from November to April without ending up with a swamp?”
What actually happens to an untouched pool over a Cyprus winter
If you switch everything off in November and walk away, here’s the typical timeline:
- November–December: Leaves and debris accumulate. Water still looks fine. Chlorine slowly depletes.
- January–February: Rain dilutes the chemistry further. Dust storms deposit fine Sahara sand across the surface, which sinks and feeds algae with phosphates. The water starts to look dull.
- March: Daytime temperatures climb past 20°C. Algae, which grows slowly in cold water, wakes up fast in warm, unchlorinated, nutrient-rich water.
- April: The pool is green. Sometimes very green.
The cruel irony is that the pool usually collapses right before you want to use it. And a full green-pool recovery — shock treatment, algaecide, days of filtering, sometimes an acid wash — typically costs more than an entire winter of reduced maintenance would have.
Your three real options
Option 1: Keep it running on a reduced schedule (what we recommend for most pools)
The pool stays open, the pump runs fewer hours per day, and maintenance visits drop from weekly to bi-weekly. Water stays balanced and clear all winter.
Best for: most villa pools, anyone who might use the pool on warm winter days, holiday rentals with off-season bookings, and anyone who wants a zero-drama spring.
Pros: No opening or closing costs. The pool always looks good — which matters for rentals and for property value. Small problems get spotted early, before they become equipment failures. And you can actually swim during those 25°C February heatwaves we seem to get every year now.
Cons: You’re still paying for some maintenance and electricity through winter, though far less than in summer.
The maths: Bi-weekly winter service costs roughly 30–40% less per month than summer weekly service, and pump running costs drop sharply with reduced hours. Over five winter months, most owners spend less this way than the combined cost of a proper closing, spring opening, and the recovery work an imperfect closure often needs anyway.
Option 2: A proper “soft close” with a cover
The pool is chemically balanced, shocked, treated with a long-life algaecide, and covered with a quality winter cover. The pump still runs briefly each day (or a few times a week), and someone checks the water monthly.
Best for: owners abroad all winter, pools that genuinely see zero use from November to April, and owners who want the lowest possible winter spend.
Pros: Lowest running cost. A good cover keeps out the leaves and most of the dust, dramatically reducing the nutrient load that feeds algae.
Cons: Upfront cost of a decent cover (cheap ones fail fast in Cyprus sun and wind). The pool is unusable and, frankly, a covered pool isn’t much to look at. And “soft close” does not mean “no attention” — an unchecked covered pool can still go green underneath, and you won’t know until you peel the cover back in April.
Important: in Cyprus we do not recommend draining pipework or lowering water dramatically the way northern-European guides suggest. It’s unnecessary in most of the island, and a partially drained pool is at risk of structural and liner problems, especially with our winter groundwater levels.
Option 3: Switch everything off and hope
We include this only for completeness. It’s the most popular option in Cyprus and by far the most expensive one — you just pay for it in April instead of January. If the choice is between a haphazard shutdown and a soft close done properly, choose the soft close every time.
Special considerations for Cyprus pools
Dust storms. Sahara dust events happen year-round but feel worse in winter and spring when the pool isn’t being cleaned weekly. That orange film isn’t just ugly — it’s rich in phosphates, which is algae food. After any significant dust event, a pool on reduced service should be skimmed and the filter checked, whatever the schedule says.
Rain and overflow. Winter is when Cyprus gets nearly all its rain. Heavy rainfall dilutes chemicals, drops pH, and can overflow the pool, washing garden soil and fertiliser into the water. After a serious storm, the water should be rebalanced.
Hard water and scale. Cyprus mains and borehole water is hard. In winter, when circulation drops, calcium is more likely to settle as scale on the waterline and in the heater or salt cell. Keeping some circulation and correct pH through winter is the cheapest scale prevention there is.
Troodos and hillside pools. If your pool is at altitude — Platres, Kakopetria, the higher villages — frost is a genuine possibility and a fuller winterisation, including equipment protection, is worth doing. Talk to us about your specific location.
So — should you close your pool?
Our honest recommendation, having maintained pools across the island through many winters:
- If you’re in Cyprus over winter, even part-time: keep it open on a reduced bi-weekly schedule. It costs little more than closing, the pool always looks superb, and you keep the option of a winter swim.
- If you’re away from November to April: do a proper soft close with a good cover and a monthly check — not a switch-off-and-leave.
- Whatever you choose: don’t do nothing. The pools we’re called to rescue in April are almost never the closed ones or the maintained ones. They’re the abandoned ones.
Frequently asked questions
When should I switch to a winter schedule? Usually late October or November, once water temperature drops below about 18°C and pool use stops. We’ll typically suggest the switch at your regular visit.
How many hours should the pump run in winter? As a rule of thumb, 3–4 hours a day is enough for most residential pools in a Cyprus winter, versus 8+ in summer. Your pool’s volume and filter size determine the exact figure.
Can algae really grow in cold water? Slowly, yes — and Cyprus water rarely stays cold for long. One warm week in February is enough to kick-start a bloom in unbalanced water.
Is it cheaper to drain the pool completely? No — and please don’t. An empty pool in winter risks serious structural damage from groundwater pressure, and refilling a large pool is expensive in a country where water isn’t cheap. Pools should only be drained for specific repair or deep-clean reasons, and only briefly.
What does a winter schedule cost? Less than you’d think — bi-weekly winter visits typically run well below summer rates. See our pricing or call for a quote based on your pool.
