Pool Water Evaporation in Dubai: How Much You Lose in Summer
By WaterLink Team · Published · Updated
How much water does a pool lose to evaporation in Dubai?
Dubai's heat, sun and dry wind make pools lose water fastest in summer. Measure your own loss with the bucket test: each 1 cm drop on a 40 m² pool is 0.4 m³, about 106 US gallons. A pool cover is the most effective way to cut evaporation. For top-ups, WaterLink delivers sweet water from 200 gallons.

Evaporation speeds up with heat, strong sun, dry air and wind — and a Dubai summer has all four. Research highlighted by the Royal Geographical Society has looked at how much water UAE pools lose this way; it’s a real share of household water use in villa communities.
Splash-out, backwashing the filter, and leaks add to the loss.
Measure your own loss: the bucket test
This simple test tells you whether you’re losing water to evaporation or to a leak:
- Put a bucket on the pool’s top step, and fill it with pool water to the same level as the pool.
- Mark the water level inside the bucket and on the pool wall.
- Turn off auto-fill. Leave it for 24 hours (pump running as normal).
- Compare the two drops.
- Both dropped by about the same amount → it’s evaporation.
- The pool dropped more than the bucket → you may have a leak. Call your pool company.
Turning centimetres into gallons
Water lost (m³) = pool surface area (m²) × level drop (m)
Example: a 10 × 4 m pool (40 m²) that drops 1 cm (0.01 m) has lost 0.4 m³ — about 106 US gallons.
| Pool surface | 1 cm drop | 3 cm drop | 5 cm drop |
|---|---|---|---|
| 30 m² | 79 gal | 238 gal | 396 gal |
| 40 m² | 106 gal | 317 gal | 528 gal |
| 60 m² | 159 gal | 476 gal | 793 gal |
How to cut evaporation
- Use a pool cover when the pool isn’t in use. It’s the single most effective step.
- Reduce wind across the water with planting, walls or screens.
- Lower water features — fountains and waterfalls increase evaporation.
- Keep the water temperature sensible — heated pools lose more.
- Fix leaks found in the bucket test.
Planning pool top ups
Topping up with a garden hose works for small losses but can take hours and may strain a villa’s mains supply in summer. A small tanker top-up is quicker:
- 200–500 gallons covers a few centimetres on a typical villa pool.
- Schedule top-ups weekly or fortnightly in summer rather than letting the level fall below the skimmer.
- Tell your pool company after a top-up so they can rebalance chemicals.
Book pool top-up water by tanker, or set up scheduled supply for the summer.
