Summer is the peak season for pool enjoyment. Whether you’re lounging by the water or diving in for a quick swim, maintaining your pool properly ensures safety, cleanliness, and cost efficiency. While many pool owners consider covering their pools during the off-season, a common misconception is that pool covers are unnecessary during the summer. This article will explore the reasons why using a pool cover in summer might be one of the best decisions you can make for your pool’s upkeep and your wallet.
Why Summer Pool Maintenance Matters
Before delving into the specifics of pool covers, it’s important to understand the challenges that come with summer pool maintenance. Increased usage, higher temperatures, more sunlight exposure, and frequent outdoor debris all contribute to a more demanding maintenance routine.
Increased Pool Usage in Summer
During the warmer months, family gatherings, backyard parties, and spontaneous dips all lead to increased wear and tear on both the water quality and the physical structure of the pool. More people mean more bacteria, dirt, and chemicals needed to balance the water.
Higher Evaporation Rates
According to the U.S. Department of Energy, a pool can lose up to an inch of water per day during hot summer weather due to evaporation. Replacing that water not only increases your water bill but also strips the pool of chemical balance, affecting both safety and maintenance costs.
UV Exposure and Chemical Breakdown
Ultraviolet rays from the sun can quickly degrade chlorine and other sanitizing agents used in the pool. As a result, pool owners often need to add more chlorine to counterbalance the sun’s effects, increasing both cost and health concerns from overexposure to chemicals.
So, how can you combat these issues? The simplest and most effective solution is to start using a pool cover—yes, even in summer.
The Benefits of Using a Pool Cover in Summer
Contrary to what many believe, pool covers offer significant advantages during the summer months. From reducing water evaporation to protecting against debris and improving energy efficiency, the benefits are far-reaching.
1. Reduced Water Evaporation
As previously noted, evaporation is a major concern in summer. Using a pool cover can reduce this loss by up to 90%. This doesn’t just save water—it saves money and effort tied to refilling and rebalancing your pool consistently.
2. Lower Chemical Usage
Pool covers help retain chemicals like chlorine by protecting the water from direct sunlight and airborne contaminants. A covered pool stays cleaner longer, meaning fewer chemical additions to maintain safe swimming conditions. This also results in a more stable pH balance and less equipment wear over time.
3. Improved Energy Efficiency
If your pool has a heater—whether gas, electric, or solar—a pool cover acts as an insulating blanket, reducing heat loss at night and keeping the water warmer. In fact, the U.S. Department of Energy reports that pool covers can reduce heating costs by up to 70%. This means you can enjoy warm water for longer with significantly lower energy usage.
4. Reduced Debris Accumulation
Leaves, pollen, insects, and even small animals can end up in your pool without a cover. Removing such debris manually or through filters takes time and can strain your pool cleaning systems, especially if you’re on vacation or busy during the week. A pool cover—especially a solid or leaf-rated model—prevents this unnecessary mess.
5. Safer Swimming Environment
While safety covers are more commonly associated with pool closures during winter, modern summer cover options (especially mesh safety covers) offer additional layers of protection by restricting unauthorized access. This is particularly important if you have young children, pets, or guests who may not be experienced swimmers.
6. Environmental Benefits
Using a pool cover helps conserve natural resources by reducing water waste and lowering chemical and energy consumption. For environmentally conscious pool owners, this offers a tangible way to make their pool more sustainable without sacrificing enjoyment or cleanliness.
Types of Pool Covers for Summer Use
Not all pool covers are created equal. Choosing the right cover involves careful consideration of your climate, usage habits, and the type of pool you own. Here’s a breakdown of the most common summer pool covers:
Thermal Pool Covers (Solar Blankets)
Also known as solar blankets, thermal covers are translucent covers made of UV-stabilized polyethylene bubbles. They trap heat from the sun and reduce evaporation and chemical loss.
Best for: Pool owners looking to retain heat while reducing chemical and water loss.
Safety Covers (Mesh Covers)
Mesh covers are tightly woven safety covers that sit securely over the pool. They allow water to pass through but are strong enough to support the weight of a person or pet.
Best for: Family safety and debris reduction without trapping heat in the pool.
Tarpaulin Covers
These are heavy-duty, solid covers made from vinyl or polyester materials. They provide excellent heat retention and debris protection, but may make the water feel warmer than desired during hot weather.
Best for: Pools in hot climates where keeping the water cool isn’t the primary objective.
Automatic Pool Covers
These high-end covers roll on and off the pool with the push of a button, offering ease of use and maximum efficiency in water and chemical conservation.
Best for: Long-term investment in pool safety, cleanliness, and energy savings.
| Cover Type | Insulation Level | Debris Protection | Safety | Cost |
|---|---|---|---|---|
| Thermal Cover | Medium–High | Low–Medium | Low | Low–Medium |
| Mesh Safety Cover | Low | High | High | Medium–High |
| Standard Tarp | High | High | Medium | Medium |
| Automatic Cover | High | High | High | Very High |
Addressing Common Concerns About Summer Pool Covers
There are several misconceptions that deter pool owners from using covers during the summer. Let’s clarify some of the most common ones with real facts and insights.
“Pool Covers Heat the Water Too Much in Summer”
While it’s true that some covers (like tarp covers and solar blankets) retain heat, not all of them are designed to do so. Mesh safety covers, for instance, allow water and air to pass through and do not significantly alter the temperature of the pool.
Solution: If you’re concerned about overheating, choose a mesh or lighter material cover that minimizes insulation but maximizes protection from debris and evaporation.
“Using a Pool Cover Is Inconvenient”
This concern mainly applies to older models that required heavy labor to apply and remove. However, modern pool covers—especially automatic ones—are easier to manage than ever. Even manual covers, with proper installation and storage systems, no longer pose significant inconvenience.
Solution: Invest in a lighter weight thermal blanket or a fully automatic roller system for hassle-free management.
“Pool Covers Reduce Algae Growth, So Why Bother?”
Actually, many believe that a covered pool is less likely to develop algae because it limits sunlight exposure. However, the opposite can be true if chlorination levels aren’t maintained. Covering a pool when not in use can help retain chlorine levels and reduce the risk of algae formation.
Solution: Combine smart chlorination practices with proper cover usage for optimal results year-round.
“Debris Isn’t a Big Problem During Summer”
On the contrary, summer brings increased pollen, bugs, windblown leaves, and even dust or sand in certain regions. Without a cover, your weekly skimming and filter work will dramatically increase.
Solution: Use a strong mesh or mesh-bottomed solid cover for optimal debris management.
How to Choose the Right Summer Pool Cover for Your Needs
Choosing the right pool cover involves analyzing your location, climate, and lifestyle. Here’s how to optimize your decision:
Climate Consideration
- Mild summers: Thermal covers can enhance swimming comfort by retaining warmth.
- Extremely hot areas: Mesh covers reduce debris without retaining excessive heat.
Pool Usage Frequency
If you use your pool daily and prefer spontaneous swims, a thermal blanket or automatic cover would be ideal. These can be easily removed and replaced in minutes, minimizing disruption.
Budget
While high-end safety covers and automatic systems come with a steep price tag, affordable solar blankets or standard tarps are suitable for homeowners looking for a short-term or budget-friendly solution.
Available Storage Space
If you have limited storage, automatic or rollable thermal covers are optimal. Solid tarp covers can take up considerable space when not in use and might require a dedicated reel for efficient handling.
How to Properly Use and Maintain a Pool Cover in Summer
Using a pool cover involves more than just throwing it on the water. Proper care extends the life of your cover and ensures maximum performance.
Installation Guidelines
Before installation:
- Ensure the pool water level is appropriate (halfway up the skimmer is ideal).
- Clean the pool thoroughly to avoid trapping dirt underneath the cover.
When installing:
- Make sure the cover overlaps the edges of the pool adequately to avoid shifting or blowing away.
- Use water bags, anchors, or a roller system to secure the cover in place.
Maintenance Tips
Regularly inspect your cover for tears, holes, or signs of degradation. Clean it once a month with a mild detergent and ensure it’s dry before storing. Avoid exposing it to sharp objects or prolonged UV exposure when not in use.
Removal Frequency
While it’s not necessary to remove the cover every day, regular check-ups to skim debris that settles on it and test chemical levels beneath can ensure water balance isn’t compromised. If the cover is causing the water to become too warm, simply leave it off midday during high temperatures or opt for a lighter-weight model.
Conclusion: Yes, You Should Use a Pool Cover in Summer
Despite common misconceptions, using a pool cover in summer offers compelling advantages including reduced evaporation, lower chemical usage, energy savings, and enhanced safety. With the wide variety of pool covers available today, it’s easy to find a solution that fits your climate, budget, and usage needs.
Whether you opt for a solar blanket, mesh safety cover, or fully automatic system, the investment you make in a quality cover pays off in cleaner water, a safer environment, and significant cost savings over time. As summer approaches, consider covering your pool not as a barrier, but as a shield—protecting your pool against the elements and ensuring it remains a clean, enjoyable place all season long.
Invest in a pool cover this summer, and you’ll find that your pool maintenance routine becomes more efficient, eco-conscious, and economical without sacrificing enjoyment.
Will a pool cover heat up my pool during the summer?
Using a pool cover during the summer can indeed influence the temperature of your pool. Solar pool covers, specifically designed for this purpose, are capable of trapping the sun’s heat and transferring it into the water, effectively warming the pool. This can be particularly advantageous in cooler climates where summer temperatures may still leave the water feeling brisk. The effectiveness of this heating relies on the type of cover chosen, with darker-colored solar covers typically absorbing more heat.
On the other hand, not all pool covers are intended to heat the pool. Traditional solid or mesh safety covers do not serve a heating function and may actually block sunlight if left on for extended periods. If your primary goal is to maintain a comfortable swimming temperature, selecting a solar cover is key. Be aware that using these covers for extended hours during peak sun may sometimes result in overheating, so monitoring and occasional removal can help maintain optimal water temperature.
Does using a pool cover in summer reduce evaporation significantly?
Yes, one of the most effective ways to reduce evaporation from your pool during the hotter summer months is by using a pool cover. When the water surface is exposed to the sun and wind, evaporation rates can rise dramatically, especially in arid or windy climates. A properly fitted pool cover acts as a barrier, preventing water molecules from escaping into the air and thereby conserving a significant amount of water over time.
In addition to reducing evaporation, pool covers help maintain chemical balance, as less water loss means fewer fluctuations in chemical concentration. This leads to less frequent refilling and reduced need for added treatment chemicals. The cumulative effect is not only cost savings but also a more stable and swimmer-friendly pool environment. Both liquid solar blankets and traditional solid pool covers contribute to this effect, though the former are specifically designed to work while still allowing swim access.
Are pool covers safe to use when swimming is frequent during summer?
Pool covers can be safely used during periods of frequent swimming, particularly if they are properly installed and maintained. Mesh safety covers and solid covers can be designed to accommodate regular use, with some models allowing for easy, partial removal and replacement. It is crucial, however, to re-cover the pool promptly after each swim to maintain safety and prevent unauthorized access, especially if children or pets are present.
Automatic pool covers are especially convenient for busy households where swimming occurs multiple times a day. These systems allow for quick, motorized deployment and retraction, significantly reducing the time and effort needed to handle a manual cover. However, even with easy access, safety guidelines should always be followed. Never leave the cover only partially deployed or use a cover while swimming, as this could lead to entrapment or tripping hazards. Always ensure the cover is fully open or closed when in or out of the pool.
Do pool covers keep out debris during the summer?
One of the primary functions of a pool cover is to keep leaves, dirt, insects, and other debris from entering the pool. This benefit becomes even more valuable during the summer when high winds, frequent backyard use, and overhanging trees can increase contamination. A properly secured pool cover acts as a protective layer that minimizes the amount of organic matter and particulates settling into the pool water.
Using a cover to keep debris out reduces the load on your filtration system and decreases the time spent skimming, vacuuming, and cleaning. This allows for better water circulation and less demand on chemicals, contributing to overall pool efficiency. While mesh covers allow water to drain through and remain on the pool during rain, solid covers offer maximum protection against debris and are preferred if the pool will be unused for extended periods.
Is a pool cover necessary if I use my pool every day during summer?
Even if your pool sees daily use, a pool cover still offers important benefits that should not be overlooked. By covering the pool when it is not in use—especially overnight—you can significantly reduce water loss due to evaporation, maintain a more stable water temperature, and guard against debris and contaminants entering the pool. This can save you time on maintenance and reduce your overall operating costs.
That said, choosing the right type of cover for frequent use is crucial. Solar covers are ideal for temperature control and are lightweight enough to be quickly removed and replaced, though they may be cumbersome if used daily during peak hours. Mesh or automatic safety covers are better suited for homes prioritizing safety and convenience. The key is to establish a routine that includes quickly covering the pool after use to maximize benefits without hindering accessibility.
Can pool covers help save on chemical usage in the summer?
A pool cover can significantly reduce the amount of chemicals required to keep your pool water balanced during the summer. By limiting exposure to sunlight and airborne contaminants, a cover helps prevent the breakdown of chlorine and reduces the introduction of organic matter, both of which contribute to higher chemical consumption. Covering your pool when it’s not in use protects your chemical investment and ensures a more stable, sanitized environment.
In addition, pool covers reduce water evaporation, which means less water loss and fewer swings in pH and alkalinity. As a result, pool owners who consistently use covers often report lower monthly expenses on chlorine, algaecides, and other treatments. For maximum chemical savings, it’s best to combine cover usage with proper circulation and regular testing to ensure consistent water quality.
Do all pools benefit from summer cover use, or are there exceptions?
Most pools will benefit from the use of a cover during the summer, but the extent of those benefits depends on climate, pool usage, and local conditions. In regions with high temperatures, intense sun exposure, or water restrictions, a pool cover becomes particularly valuable. Conversely, in areas with mild summers or near-zero evaporation rates, the benefits of using a cover may seem less critical but are still relevant in terms of safety and debris control.
Exceptions might include pools that are designed for passive use, such as natural swimming pools or those integrated into ecosystems that encourage algae and need a level of open exposure. Additionally, those with integrated smart temperature regulation systems or frequent, automated maintenance may see reduced need for covers. However, for the vast majority of residential pools, even during heavy summer use, a cover makes a strong contribution to efficiency, safety, and cost management.
