How to Open Your Pool in the Spring in the Var: The Complete Checklist for 2026
Opening your pool in the spring is a crucial step to ensuring clean water and a reliable system all summer long. In the Var and the Gulf of Saint-Tropez, where the summer season often begins as early as April, planning ahead for this restart is essential. Whether you own a villa in Cavalaire-sur-Mer, La Croix-Valmer, or Rayol-Canadel, a properly executed pool opening prevents unpleasant surprises and guarantees crystal-clear water from the very first dips.
At POOLRITUAL, a leading pool specialist in the Gulf of Saint-Tropez, we help dozens of homeowners with this process every year. Here is our comprehensive, step-by-step guide to a successful pool opening.
Choosing the right time to open your pool in the Var
The question comes up every year: when should you open your pool in the Provence-Alpes-Côte d'Azur region? Unlike regions further north, the Var enjoys early sunshine. Water temperatures often start to rise as early as late March or early April, which can lead to algae growth if the pool isn't treated in time.
The basic rule: open your pool when the water temperature consistently exceeds 12°C. Below that temperature, algae and bacteria grow slowly. Above that temperature, they multiply rapidly if the water isn’t treated. In the Gulf of Saint-Tropez, this threshold is often reached as early as mid-March.
Waiting too long always makes opening the pool more difficult: green water, mineral deposits, and clogged filters. It’s best to open the pool one to two weeks before your first planned swim.
Remove and clean the winter cover
This is the first practical step in preparing your pool for the season. Whether you have a roller shade, a winter cover, or a bar-style cover, here are the steps to follow:
Gently remove the cover, taking care not to dislodge any debris that has accumulated in the pool.
Clean the blanket thoroughly before storing it: mold, dead leaves, and mineral deposits can damage it if it is stored while dirty.
Visually inspect the cover for any tears or wear and tear that would require repair before the next winter.
Store the tarp in a dry place out of direct sunlight to protect the material.
If your pool is equipped with an automatic roller cover, be sure to check that the motor is working properly after several months of inactivity.
Restart the filtration system and technical equipment
Filtration is the heart of your pool. After winterizing, there are several checks you should perform before restarting the system:
Check the water level: it may have dropped slightly over the winter. Top it off before starting the pump.
Gradually reopen the suction and discharge valves to prevent water hammer.
Drain the pipes if you have performed active winterization with partial draining.
Clean or replace the sand filter, cartridge, or diatomaceous earth filter, depending on the type of filtration system.
Check the condition of the pump's pre-filter and clean the basket.
Test the heat pump or heating system if your pool is equipped with one.
In the Var region, where hard water is common, it may be necessary to descale the pump and nozzles after winter, especially if you did not use anti-scale products during winterization.
Water treatment: restoring the pond's chemical balance
This is often the most technical step in preparing a pool for the season. The water composition has changed over the winter, and a complete chemical rebalancing is essential before anyone swims in it.
The parameters to test first:
pH: ideally between 7.2 and 7.4. An unbalanced pH makes treatments ineffective.
TAC (total alkalinity): between 80 and 120 mg/L to stabilize the pH.
TH (hydrotimetric title): between 10 and 25°f to minimize scale and corrosion.
Chlorine or salt level (for electrolysis pools): Adjust to the recommended level.
Phosphate levels: often high after winter, they promote algae growth.
Once these tests have been performed, adjust each parameter in the following order: TAC, then pH, then disinfectant. An initial chlorine shock is often recommended to eliminate winter bacteria. Let the filtration system run for 24 to 48 hours before the first swim.
POOLRITUAL offers a comprehensive water analysis every time a pool is opened in the Gulf of Saint-Tropez, along with precise adjustment of all parameters.
Cleaning the pool and pool decks
After several months of winter storage, even with a cover, deposits build up on the walls and bottom of the pool. A thorough cleaning is necessary before the water is put back into circulation.
Scrub the sides and bottom to remove biofilms and limescale deposits.
Use a vacuum cleaner or a wet/dry vacuum to remove the debris from the bottom.
Clean the skimmers, jets, and handrail.
Check the condition of the pool lining: liner, tile, or shotcrete—any cracks or peeling must be repaired promptly.
Clean the pool deck and coping to remove algae and winter buildup.
If the water is very green or cloudy, flocculation can speed up the recovery process before restarting the suction.

FAQ — Your Questions About Pool Opening in the Var
How much time should you set aside for opening your pool in the spring?
On average, it takes a professional between 3 and 6 hours to prepare a pool for the season, depending on the pool’s size and its condition after winter. You should then allow 24 to 48 hours of filtration before the water is ready for swimming.
Can you set up your own pool without any technical knowledge?
Yes, for simple pools and if you have experience. However, testing the water and adjusting the equipment require a basic understanding to avoid costly mistakes. For complex systems (such as an integrated spa, an electrolysis unit, or an automatic cover), it is recommended that you hire a professional pool specialist.
