When and How to Open up Your Swimming Pool for the Summer

You might have started to notice that we are seeing some exciting double figures in the weather forecasts lately.

Easter has come and gone and this is usually a good marker of time for when you should start thinking about how to open your swimming pool for the summer!

However, it can still be a little chilly and you might be wondering, ‘what’s the hurry?’.

Firstly, if you leave this too late you will end up with a warm unopened pool full of growing bacteria and algae. In fact, this is likely to be the case anyway if you did not invest in correctly closing your swimming pool for the winter (please see our Winterisation services).

When to Open up Your Pool

Reopening a pool can be a difficult task that needs to be done each year.

Before you can open your pool, you need to make sure the temperatures are high enough! You generally want to have temperatures consistently around 15 degrees Celsius/60 degrees Fahrenheit.

How to Open up Your Swimming Pool

There are many steps you need to take to open your swimming pool. Here is how our experts would recommend opening your swimming pool in the summer. 


The most important thing you need to do when you're opening up your swimming pool is to prepare. You need to block out enough time, have all of the supplies, and understand what steps you need to take. 

Some of the materials you will need are a leaf net, a pool vacuum, gloves to protect your hands, a hose to fill your pool, chemical test strips, as well as all of the chemicals you need to add to your pool.

You can buy these in our chemical packs that includes all the different chemicals you will need. 

Clean the Cover

Next, you will want to clean and remove the pool cover you had on during the winter months.

Dried debris can be easily removed and brushed or swept off. You'll need a soft bristle brush to remove any debris that built up over the winter.

You can also use a high-pressure hose to clean any remaining debris off of your pool cover.

Once you have cleaned the cover with soap and other cleaners, leave it in a flat area to dry. As soon as it has dried, make sure you store your cover in an area that is free from moisture and pests. 

Clean Debris From the Pool

The next step to pool summerisation is to clean the pool itself.

There may be algae growing in your pool, or there may be debris or other things floating in the water. To give it a good cleaning, you will first want to use a leaf net to remove debris from the surface of the pool.

You will also need to use a pool vacuum to clean the bottom of the pool from any debris or buildup. 

Doing a preliminary clean of the pool before you install chemicals will help the process go a bit faster!

Reinstall Pool Accessories

At this point, you will be able to install equipment and accessories that you had removed over the winter months.

These include ladders, slides, diving boards, hand grabs, and more! You can clean each of these accessories before you reinstall them into your pool. 

You can also install newly purchased equipment, like pumps, heaters, and new filters. Each of these should come with its own installation instructions.

Set Up Your Pool

To set up your pool, you will first begin by filling your pool to its normal level. You can do this with a garden hose.

Most pools should be filled to the midpoint on the waterline. Next, you will install drain plugs, make sure your pumps are working properly, and turn on any filters that you have!

Make sure all your valves are in the right position and are working properly. When you turn these on, you can check to see if any have been damaged or are not working. 

Add Chemicals and Sanitation Products

The final and most important step in the pool summerisation process is to make sure you treat your water properly with each sanitation product.

Once these are included in your pool, you can use test strips to check the chemical levels and have them checked by a professional.

Generally, you want to leave these chemicals in your pool for about 24 hours before you test these. Some of the things you will test are the pH level, chlorine content, and more.

Once more, you will want to thoroughly brush your pool to loosen any other debris or sediment at the bottom of the pool. After this, let your filtration system run to finish cleaning your pool. Then, enjoy your pool all summer!
