How much water does a pool lose due to natural evaporation?

Every pool naturally loses water through evaporation. The amount varies depending on the season, temperature, wind, and humidity. Knowing these values helps you distinguish between normal evaporation and a possible leak.

☀️
Summer
Normal loss: 2 – 3 cm/week
(~0.3 – 0.4 cm/day)

More heat, more sun, and more wind accelerate evaporation.

❄️
Winter
Normal loss: 0,5 – 1 cm/week
(~0.07 – 0.14 cm/day)

Low temperatures and less sun exposure reduce evaporation.

⚠️

Practical rule: If the water level in your pool drops more than 3 cm per week in summer or 1 cm per week in winter, it is likely not just due to evaporation. It is advisable to have a professional inspection to rule out leaks.

Calculator by Meter Reading

Measure the leak directly from your water meter by observing how many liters move per minute.

How to read the meter?

1
Close everything.

Turn off all the faucets, appliances, and toilets in your home.

2
Locate the counter

Go to your water meter and take a look at the small red dial (the smallest one). Each mark that moves forward equals 1 centiliter (cl).

3
Wait 1 minute

Observe how many centiliters (marks) move on the wheel in exactly 1 minute.

4
Enter the data

Write below how many centiliters were moved. If none were moved, you have no leak!

⚠️

Important: If the dial of the meter moves with everything closed, you have a leak. The faster it spins, the greater the loss.

Frequently Asked Questions

Everything you need to know about water leaks

A pool loses between 3 and 5 millimeters a day (0.3 – 0.5 cm) due to natural evaporation, depending on temperature, wind, and humidity. If the drop exceeds 5mm/day consistently, you probably have a leak.
Do the cube test: place a water cube on the pool step and mark the water level inside and outside the cube. After 24 hours, if the pool level has dropped more than that of the cube, you have a leak. You can also use our calculator, and if the drop exceeds 0.5cm/day, it is very likely that there is a leak.
It depends on the flow. A simple dripping faucet can cost between 15 and 30€ per month. A leak in a concealed pipe can exceed 200€/month just in wasted water, not counting the structural damage it can cause.
