Pool maintenance in winter is essential to ensure that it is in optimal condition for use when the hot season arrives.
During the cold months, many people tend to neglect pool care, but this is the perfect time to carry out preventative tasks that will extend the life of your pool and ensure that the water is clean and balanced when spring arrives.
Below, we offer a complete guide to maintaining your pool during winter, with practical tips and key steps to avoid common problems.
1. Clean the pool before closing
Before winter sets in, give your pool a thorough cleaning. This includes removing leaves, dirt and other debris from the bottom and walls of the pool. Use a pool vacuum to remove any debris that may have built up. Also clean skimmers and pumps, making sure there are no clogs.
In addition, to ensure that your pool water remains in perfect condition during the cold months, it is advisable to add an algaecide to prevent algae growth and a pool winterizer , which helps keep the water protected from impurities and bacteria, ensuring that your pool is ready for the next use without problems.
2. Balance pH and water treatment
It's critical to keep your pool water balanced during the winter. Check the pH, alkalinity, and chlorine levels before closing the pool. The water must be balanced to prevent problems such as surface corrosion or algae growth. You can add specialized chemicals such as pH reducer or chlorine to stabilize the pH and keep the water sanitized.
3. Install a winter cover
A pool cover is one of the most important items to maintain during the cold months. Not only does it protect the water from dirt, but it also helps maintain temperature and prevents water from freezing in colder weather. Make sure the cover is tight-fitting and free of gaps to prevent water or debris from seeping in.
4. Reduce the water level
To prevent water from freezing and damaging walls or filtration systems, it is advisable to slightly lower the water level in the pool. This helps prevent the expansion of frozen water, which can cause damage to pumps, skimmers, and other components of the pool system.
5. Disconnect and protect the equipment
During the winter, it's important to protect pool equipment such as pumps, filters, and heaters. Unplug them and, if possible, remove them from the pool to store them in a dry, frost-free location. If removal is not possible, be sure to drain water systems and apply antifreeze to prevent residual water from causing freeze damage.
6. Check water levels periodically
Even if the pool is not being used during the winter, it is important to monitor water levels periodically. This ensures that there are no extreme fluctuations that could damage the system or the pool structure. If there are leaks or water evaporates, the water level needs to be replenished to prevent the systems from running dry.
7. Check pumps and filters
Before winter arrives, make sure that your pumps and filters are in perfect condition. If you find any leaks or faults, repair them immediately. During winter, even when the pool is not in use, it is important to run the filter system intermittently to prevent the water from stagnating and becoming a breeding ground for bacteria. If necessary, use flocculant to improve water quality.
8. Inspect the pool regularly
Even if your pool isn't used in the winter, perform regular inspections to make sure there aren't any problems. Check the covers, filtration system, and water levels. If you find any leaks or problems, act quickly to prevent them from getting worse during the winter. If you detect debris or algae, use bromine or a reducer to remove impurities.

Pool Maintenance According to the Climate of the Area
Local climate plays a key role in pool maintenance during winter, as weather conditions directly affect the condition of the water and pool components.
In countries like Spain, where climatic variations can be extreme depending on the region, it is crucial to take into account factors such as snow, wind and heavy rain.
1. Areas with snow or extremely low temperatures
In regions of Spain where winter is very cold and snow falls, such as in the north or in mountainous areas, the risk of freezing is higher. Pool water can freeze if proper precautions are not taken, which can damage both pool surfaces and filter systems and pumps.
To do:
- Lower the water level : Lower the water level below the skimmers to prevent water from freezing in these areas. This will help prevent damage to the filtration system.
- Cover the pool properly : Use a winter cover that is resistant to low temperatures and prevents snow and ice from coming into contact with the water. Covers must be strong enough to withstand the weight of accumulated snow.
- Antifreeze for the system : Be sure to use antifreeze in the pipes and filtration system to prevent water in the equipment from freezing and causing damage.
- Check the pump : If your pump is not cold-resistant, consider emptying it and removing it to prevent it from breaking due to freezing.
2. Areas with strong winds
In some regions of Spain, such as the Mediterranean coast or areas near valleys, strong winds can be a challenge for pool maintenance. These winds can bring leaves, dust, branches and other debris that accumulate in the pool, increasing the need for cleaning.
To do:
- Install a Wind-Resistant Cover : In addition to protecting your water from the elements, a high-quality cover will prevent the wind from blowing leaves and other debris into your pool.
- Check the walls and bottom of the pool regularly : Due to wind, debris can quickly build up, requiring frequent cleaning to prevent the proliferation of bacteria and algae.
- Clear the area around the pool : Make sure there are no trees, bushes or structures nearby that can easily shed branches or leaves during storms or strong winds.
3. Areas with heavy rains
In many areas of Spain, especially in the north and northwest, heavy rainfall is common during winter. If not managed properly, rainfall can upset the water balance, increasing the amount of impurities and diluting chemicals, which can cause water quality problems.
To do:
- Check the water level : After heavy rain, the water level may rise, which can affect the pool structure and system components. Check the level regularly and adjust as needed.
- Constant filtration and cleaning : Rain can drag more waste and contaminants into the pool, so it is necessary to increase the frequency of filtration and cleaning of the pool.
- Balance water quickly : Rainfall can dilute the chemicals that keep your water balanced. After a heavy rain, check your pH, alkalinity, and chlorine levels to keep your water clean and safe.
4. Areas with temperate or frost-free climates
In areas where winters are mild, with no frost or snow, such as some regions in southern Spain, problems with freezing are less common. However, it is equally important to carry out preventative maintenance to avoid algae growth and the accumulation of debris.
To do:
- Keep the filtering system running intermittently : Even if temperatures are not extremely low, it is recommended to continue using the filtering system sporadically to prevent the water from stagnating and promoting the proliferation of bacteria.
- Use of protective covers : Despite the absence of frost, using a cover to protect the pool from leaves and dirt is still recommended.
