Dubai Heat Survival Guide: Cooling Tips to Lower Your DEWA Bill
Most of the saving comes from a few plain habits: keep the thermostat at 24°C in auto mode, which DEWA recommends (Gulf News, August 2026), keep the sun out with curtains or blinds in the hottest part of the day, and stop cool air escaping through gaps around doors and windows.
A summer audit of your home, or of a property you are viewing, done before the heat arrives, shows where cool air is lost and where the sun gets in. This guide covers what to check, which habits help and what to look for in a building.
How Do You Check a Property's Cooling Before You Buy?
The Summer Audit Checklist
A viewing is a chance to see how well a home holds cool air and keeps the sun out. Check these three things.
1. Window Seal Integrity:
- Run a hand along closed window edges feeling for drafts
- Poorly sealed windows and sliding doors let cool air out
- Escaping cool air makes the AC work harder and pushes bills up
2. AC Vent & Ceiling Analysis:
- Look for water stains or patches near AC vents
- Stains can point to condensation issues, so ask the seller or building management about them
3. Sun Orientation Assessment:
- South/west-facing: these units take the afternoon sun
- Good natural light, but they need more shading in summer
- Check the glass and look for deep balcony overhangs that give natural shade
Features Worth Looking For:
- Double-glazed windows
- Cross-ventilation layouts that let air move through the home
- Balcony overhangs or other fixed shading
What Is the Best AC Temperature for Dubai Summer?
The 24°C Setting
DEWA recommends keeping the thermostat at 24°C and using auto mode, if it is available (Gulf News, August 2026). Setting the thermostat lower than that makes the AC work harder and use more electricity.
Do Thermal Curtains Actually Reduce Dubai Heat?
The Case for Shading
The simplest step is to cover windows with curtains, blinds or drapes during the hottest part of the day (Gulf News, August 2026). Thermal or blackout curtains with a lined back are made to cut the light and heat that come through the glass, so the room needs less cooling.
Choosing Curtains:
- Pick a lined, closely woven fabric
- Hang the curtain so it covers the whole window and reaches the floor
- Keep it closed on the sunny side of the home through the afternoon
UV Window Film Alternative:
If you want to keep the view, such as the Dubai Marina skyline or Motor City greenery:
- The film goes on the glass, so the view stays
- It blocks UV light, which also helps protect furniture from fading
- It cuts some of the solar heat coming through the glass
What Are Best Balcony Plants for Dubai Heat?
Shade From Plants
Plants on a balcony give shade and soften the glare coming off hard surfaces.
Heat-Resistant Options:
1. Bougainvillea:
- Function: Climbing plant covering railings or pergolas
- Benefit: Natural sunshade
2. Plumbago (Blue Jasmine):
- Function: Wall planters, vertical coverage
- Benefit: Blue and white flowers, minimal pruning
3. Succulents & Dwarf Pittosporum:
- Function: Green dividers
- Placement: Along glass railings
What Building Features Help Keep a Home Cool?
Look at how the building is put together as well as the apartment itself:
- Insulation in the walls and ceiling
- Weather stripping around doors
- Reflective paint on exposed rooftops
Well-sealed homes hold cool air longer, which reduces the AC workload and DEWA costs.

The Takeaway
Summer does not have to mean freezing the apartment and accepting a high DEWA bill. A little preparation before the heat arrives does most of the work.
Action Items Before Summer:
✅ Conduct a summer audit (property viewings or your current home)
✅ Install thermal curtains or UV window film
✅ Seal window and door gaps that let air leak
✅ Add heat-resistant plants to the balcony
✅ Set the AC to 24°C in auto mode, as DEWA recommends
Choosing a Home
When comparing homes in DLRC, Arjan, JVC or Motor City, look at insulation, glazing and shading alongside price and location.

How can I reduce my DEWA bill before summer?
Set the thermostat to 24°C and use auto mode, which DEWA recommends (Gulf News, August 2026). Keep windows and doors closed while the AC runs, cover windows with curtains or blinds in the hottest part of the day, and have the AC serviced before summer.
What AC temperature does DEWA recommend?
DEWA recommends keeping the thermostat at 24°C and using auto mode, if it is available (Gulf News, August 2026). A lower setting makes the AC work harder and use more electricity.
Are curtains and window film worth using in Dubai?
Both cut the sunlight coming through the glass, so the room needs less cooling. Curtains, blinds or drapes are the simplest option, and window film lets you keep the view.
What should I check on a property viewing to avoid high cooling costs?
Check the window and sliding door seals for drafts, look for water stains near AC vents, and note which way the unit faces. South and west-facing homes take the afternoon sun, so look at the glass and the balcony shading.
Should I invest in solar panels to cut my DEWA bill?
Solar panels have a significant upfront cost, and payback depends on the system, your usage and the tariff. Prioritise the simple efficiency steps first, and ask DEWA for its current rules before you decide.
