When to Open the Pool For the Season

As the warm weather approaches, most pool owners have one question: When can I open my pool?

Those in four-season climates are chomping at the bit come springtime! While there is no one-size-fits-all answer to this question, several factors must be considered before deciding.

Opening your pool too early or too late can affect the balance of your pool water and may result in costly maintenance and pool chemical usage.

Here is what you need to look out for when determining the right time to open your pool:

A constant daytime temperature of 70 degrees Fahrenheit
Water temperature should be at or below 60 degrees Fahrenheit
Areas with heavy pollen should consider opening before it blooms
If opening with a pool company, their schedules will fill up fast

Daytime Temperatures Above 70 Degrees Fahrenheit

It is highly recommended to open your pool when the daytime temperature consistently stays above 70 degrees Fahrenheit.

Consistently because the spring weather can change dramatically, one day it can be 80 degrees and sunny followed by a week of temperatures below freezing. However, if you happen to catch a cold spell after the pool has been opened, run your pool pump 24/7. Water should be continuously flowing through your pipes.

Warmer temperatures provide a comfortable environment for bacteria and algae to grow, which can quickly turn your pool into a breeding ground for microorganisms.

Water Temperatures at or Below 60 Degrees Fahrenheit

Your pool should be opened before the water reaches 60 degrees Fahrenheit.

While algae can grow in any pool without proper chlorine sanitation, it grows much slower in colder water. When water hits about 60 – 65 degrees Fahrenheit, algae will bloom faster.

Opening while the water is still on the colder side gives you more time to properly open the pool, test the water with your pool kit, and ensure your water is properly balanced before the first swim.

Open Before the Pollen Starts to Fall

If you are in an area with prominent pollen, it’s highly recommended to open your pool before it starts falling.

Pollen can quickly accumulate on the bottom of your pool especially with a mesh cover, creating a breeding ground for bacteria and making it much more difficult to maintain clean and clear water.

By opening the pool and running the pump before it falls, the pollen will get filtered out of the water before reaching the bottom.

Consider The Pool Company’s Schedule

If you are still using a pool company that opens the pool, you’ll need to consider their schedule more than yours.

Their calendars will start to fill up very quickly, so make sure to call and schedule an appointment as early as possible. The last thing you want to have to happen is a scheduled opening in the middle of the summer.

An Opened Pool is Easier to Look at

Let’s face it; the winter covers are ugly to look at. It’s boring not to have the pool up and running! You won’t be the only owner itching to open the pool to see the clear blue water rippling on the surface.

The Earlier, the Better

Avoid opening a little earlier than expected. These tips will help you find the best open day that fits your schedule.

Lastly, ensure you have all the necessary chemicals to maintain water balance before opening. Sometimes, pool stores and big-box chains run out of liquid chlorine and other necessary items in late spring and early summer.

Now, go ahead and start planning your swim season! Also, check out when others in your state like to open their pool.
