Summer in Dubai is synonymous with heat, but the real challenge for homeowners and tenants is often the humidity. When outdoor relative humidity levels climb above 90% at night, that moisture inevitably tries to find its way indoors.
Without a proactive cleaning and maintenance strategy, high indoor humidity can lead to musty odors, damaged fabrics, and the rapid growth of mold. At LUMINA Property Care, we know that a crisp, fresh home requires more than just cranking up the AC. This guide outlines the essential steps to protect your property—from laundry logistics to bathroom ventilation—along with a practical weekly plan.
The Science of Indoor Humidity
To protect your home, it helps to understand what you are fighting. The ideal indoor relative humidity (RH) for health and comfort in the UAE is between 30% and 50%. Once levels creep above 60%, the risk of mold colonization increases significantly. In fact, mold and mildew can begin to grow on damp surfaces within just 24 to 48 hours.
Porous materials in your home—like linen curtains, cotton bedding, and untreated wood—are hygroscopic. This means they naturally absorb moisture from the air, acting like sponges that hold onto dampness if the environment isn't controlled.
1. Mastering the 'Dry Mode'
Your air conditioning system is your first line of defense, but simply lowering the temperature isn't always enough. Standard 'Cool' modes focus on dropping the mercury, sometimes shutting off the compressor before enough moisture has been extracted from the air.
- Switch to Dry Mode: Most modern AC units in Dubai have a 'Dry' or 'Dehumidify' setting (usually indicated by a water drop icon). This runs the fan at a lower speed, allowing the air to pass over the cooling coils for longer, which extracts moisture more effectively.
- Check Drainage: Static water in AC drainage trays is a common cause of leaks and bacterial growth. Ensure your AC maintenance covers tray cleaning to prevent blockages.
2. Laundry Logistics in High Humidity
One of the biggest mistakes residents make during the summer is air-drying laundry indoors without adequate ventilation. Drying a load of wet clothes inside can increase indoor humidity by up to 30%, creating a localized microclimate perfect for mold.
Best Practices for Summer Laundry
- Use a Tumble Dryer: Whenever possible, use a dryer to remove moisture completely before storing clothes.
- Dehumidifier Assistance: If you must dry delicate items on a rack, place them in a small, closed room with a dehumidifier running on high. Do not rely on the AC alone.
- The 'Musty Wardrobe' Prevention: Never put slightly damp clothes back in the closet. We recommend using moisture-absorbing sachets (silica gel or calcium chloride) in wardrobes and drawers to trap lingering dampness.
3. Protecting Soft Furnishings
Your sofas, mattresses, and heavy drapes are prime targets for dust mites, which thrive in humidity levels above 70%.
- Vacuum Frequently: Use a vacuum with a HEPA filter on mattresses and upholstery weekly to remove dust mite allergens.
- Airflow is Key: Pull sofas and beds at least 2 inches away from exterior-facing walls. This gap allows air to circulate, preventing condensation from forming on the cool wall surface behind the furniture.
- Professional Deep Cleans: Summer is the ideal time for professional upholstery cleaning that uses low-moisture extraction methods.
4. The Bathroom Battleground
Bathrooms are naturally wet zones, but in high humidity, they struggle to dry out between uses. This leads to 'pink slime' (a bacteria called *Serratia marcescens*) forming in corners and drains.
- Squeegee After Showers: Take 30 seconds to squeegee glass and tile surfaces after every shower. Removing the water immediately drastically reduces evaporation into the air.
- Ventilation: Run the exhaust fan for at least 20 minutes after showering. If your bathroom lacks a powerful fan, leave the door open to allow the AC to dry the room.
- Tackle Mold Early: If you spot black specks on grout, scrub immediately with a mixture of baking soda and white vinegar. These natural agents neutralize odors and kill mild surface mold without the harsh fumes of bleach.
Your Weekly Humidity Defense Plan
Staying ahead of humidity requires consistency. Use this weekly checklist to keep your Dubai home fresh and safe.
Monday: The Air Audit
- Check thermostat settings (ensure 'Auto' or 'Dry' mode is active).
- Inspect AC vents for any visible condensation or dust buildup.
Wednesday: The Mid-Week Refresh
- Pour a cup of white vinegar down kitchen and bathroom drains to neutralize odors.
- Check moisture absorbers in wardrobes; replace if filled with water.
Friday: Soft Furnishing Focus
- Strip bed linens and wash in hot water (above 60°C) to eliminate dust mites.
- Vacuum sofas, curtains, and mattresses.
- Rotate cushions to ensure even airflow exposure.
Saturday: Bathroom Deep Clean
- Scrub grout lines and shower corners.
- Wash bath mats (these trap immense amounts of moisture).
- Wipe down walls with a dry microfiber cloth.
When to Call the Professionals
Sometimes, despite your best efforts, the Dubai humidity wins. If you notice persistent musty smells, visible mold spreading on walls, or if your soft furnishings feel permanently damp, it is time for professional intervention.

FAQ: Dealing with Dubai Humidity
Q: What is the ideal temperature to keep my AC at to control humidity?
While 24°C is efficient for energy, setting your AC between 21°C and 23°C often helps remove more moisture. However, the 'Mode' (Dry vs Cool) matters more than the temperature setting alone.
Q: Can I open windows in the evening during summer?
In Dubai's summer, evening humidity is often higher than daytime humidity. It is generally best to keep windows sealed from June to September to maintain a controlled indoor environment.
Q: How do I get the musty smell out of my clothes?
Wash the clothes with a cup of white vinegar added to the rinse cycle, then dry them immediately and thoroughly. Ensure your closet has moisture absorbers installed to prevent recurrence.
Q: Does humidity affect holiday homes that are empty?
Yes, unoccupied homes are at high risk because air circulation is often reduced to save energy. We recommend keeping the AC on a localized setting or scheduling weekly checks.
