Introduction
Most people know Dubai summers are hot. But "hot" doesn't really tell the full story.
When temperatures climb above 45°C—which happens regularly during the UAE summer—the inside of a parked car can become dangerously hotter within a short time. What seems like a harmless item left on a seat or dashboard can quickly become damaged, useless, or even hazardous.
If you plan to hire a car in Dubai this summer, understanding what should never be left inside your vehicle is just as important as knowing local driving rules. From electronics and medications to aerosol cans and important documents, some everyday items simply don't belong in a parked car during extreme heat.

How Hot Does a Parked Car Get in Dubai?
Before getting into the list, it helps to understand the actual temperatures involved, because they're more extreme than most people expect. According to Gulf News, UAE outdoor temperatures regularly approach 50°C during peak summer, with the highest temperature recorded in the UAE in May 2025 reaching 51.6°C in Sweihan. Inland areas repeatedly see daily highs above 50°C throughout July and August (Gulf News, 2025).
Inside a parked car with the windows up, temperatures rise dramatically faster than the air outside. Even with external temperatures in the low 40s, the interior of a closed vehicle can hit 70–80°C within 20 to 30 minutes. Road surfaces themselves can reach 70°C according to automotive safety data cited by Gulf News experts.
That level of heat doesn't just make the car uncomfortable. It causes chemical reactions in batteries, distorts plastic housings, degrades medication effectiveness, and — in the case of aerosols and lighters, creates genuine fire and explosion risks. When you hire a car in Dubai, that vehicle is your responsibility during the rental period. Damage caused by items you've left inside can result in costs you weren't expecting. The steps below protect both you and the car.
Things You Should Never Leave in Your Car in Dubai Summer
Electronics and Battery-Powered Devices
Phones, laptops, tablets, portable chargers, and similar devices should never be left in a parked car during UAE summer and full stop. Most lithium-ion batteries begin degrading at sustained temperatures above 45°C. At 60–80°C, the battery can swell, leak, or in rare cases catch fire. The same applies to laptops and cameras. Manufacturers explicitly warn against heat exposure for exactly this reason.
Beyond the fire risk, there's also the practical damage. A phone left in a hot car for an hour can return to you with a swollen battery, a warped screen, or permanently reduced capacity. Some devices simply don't recover. And practically speaking, electronics left visible in a parked car are a theft target. Breaking a window costs a thief seconds. It costs you your device and a cracked window on a rented vehicle.
Aerosol Cans and Lighters
This is the one most people genuinely don't think about. Aerosol cans, deodorant, hairspray, sunscreen spray, air freshener are pressurized containers. The propellant inside expands with heat. In a car that reaches 80°C, an aerosol can be stored in the door pocket or glove box can explode. This isn't a worst-case hypothetical; summer car fire incidents linked to pressurized items are documented in the UAE.
Disposable lighters carry an explicit manufacturer warning to store below 45°C. That threshold is regularly exceeded inside a parked car in Dubai by early morning in July. Butane gas expands. At sufficient pressure and temperature, it ignites. Neither of these items is worth leaving behind. Take them with you, or store them in a shaded bag in the boot — not in the sun-facing interior. Gulf News summer car safety coverage explicitly lists aerosol cans, lighters, and hand sanitizer bottles among items that "can explode or ignite" in parked vehicles during UAE summers (Gulf News, 2025).
Medications
Most medications carry a storage instruction you've probably skimmed past: store at room temperature, away from heat and direct sunlight. Room temperature means roughly 15–25°C. A parked car in Dubai summer is four times that. Certain medications like insulin, some antibiotics, eye drops, liquid formulations degrade rapidly at high temperatures. Their effectiveness drops. In some cases, the chemical composition changes in ways that can be harmful. If you're managing a medical condition and driving in Dubai, keep medications in a small insulated pouch and carry them with you when you leave the vehicle. Don't rely on the glove box as storage. It's one of the hottest spots in the car.
Cash, Cards, and Valuables
Leaving cash or cards in a car is a security risk anywhere. In Dubai, it also has a practical problem: moisture. Heat and fluctuating temperatures create condensation inside a vehicle interior over time. Paper currency and card magnetic strips can be damaged. More immediately, any valuables left visible in a parked car make the vehicle a target. A rental car, in particular, signals to opportunists that the driver may be unfamiliar with the area and has possessions worth taking. Keep your wallet, passport, and cash with you at all times. If you must leave something behind temporarily, store it in the boot before parking, not after you've arrived and been seen moving things.
Important Documents
Residency cards, vehicle registration, insurance documents, business papers none of these belong in a car long-term. Prolonged heat causes paper to yellow, become brittle, and in some cases develop mildew if combined with humidity from the AC. More critically, documents left in a hired car are a liability. If the vehicle is broken into or the documents are lost, the complications extend well beyond replacing paper. Keep originals at home or in the office. If you need a document for a specific drive, take it with you when you exit the vehicle, don't use the car as a document storage solution.

Protecting Your Hired Car — What Rental Companies Expect
When you hire a car in Dubai, you accept responsibility for its condition during the rental period. That includes damage caused by items you've stored inside. Most rental agreements require the vehicle to be returned in the same condition it was collected. Fire damage, melted interior components, or chemical spills from an aerosol malfunction won't be covered by a standard insurance policy if caused by negligence. The cost comes back to you.
It's also worth noting that personal lease and long-term rental agreements in Dubai often have clearer terms around vehicle condition, something worth reviewing before signing. If you're unsure about coverage, this breakdown of getting an affordable rental deal in Dubai includes useful context on what to check.
Quick Summer Car Safety Habits Worth Building
Beyond what not to leave behind, a few basic habits make a real difference when driving a hired car in Dubai during summer:
- Park in shade wherever possible. Even 10–15 minutes less direct sun exposure meaningfully reduces interior temperature.
- Use a windshield sunshade. Reduces dashboard and steering wheel surface temperature significantly.
- Crack windows slightly when parked in a private or secure area. Allows some heat to escape without creating a security risk.
- Let the AC run for 60–90 seconds before entering a parked car in peak afternoon heat. Circulating the air first prevents the worst of the heat shock.
- Check tire pressure every few days. Heat expands air inside tires. Over-inflation on a 70°C road surface increases blowout risk noticeably.
Also, long summer drives bring their own challenges beyond car storage. If you're planning an extended trip, read our guide on how to stay alert on long drives in Dubai — fatigue in summer heat is a real combination risk.
Key Takeaways
- A parked car in Dubai summer can reach 80°C inside, high enough to damage electronics, degrade medications, and cause pressurized items like aerosol cans and lighters to explode or ignite.
- The five items to always remove before parking are electronics, aerosol cans and lighters, medications, cash and valuables, and important documents, each carries a distinct risk in high-heat conditions.
- When you hire a car in Dubai, you're responsible for the vehicle's condition during the rental period. Damage caused by heat-related incidents involving stored items can result in unexpected costs not covered by standard insurance.
FAQs
How hot does it get inside a car in Dubai summer?
Interior temperatures can exceed 80°C in a closed, parked car when outside temperatures are in the mid-40s. This can happen within 20 to 30 minutes. Road surface temperatures in the UAE summer regularly reach 70°C, adding radiant heat from below the vehicle.
Can a lighter or aerosol can actually explode in a hot car in Dubai?
Yes, this is a documented risk, not an exaggeration. Disposable lighters carry a storage warning below 45°C; car interiors in Dubai summer far exceed that. Aerosol cans are pressurized and expand with heat. Both items have been linked to car fire incidents in the region during summer months.
Is it safe to leave medication in a hire car in Dubai?
No. Most medications should be stored between 15°C and 25°C. A parked car in Dubai summer can reach three to four times that temperature. Heat degrades medication effectiveness and can alter chemical composition. Carry medications with you in an insulated pouch.
Will rental car insurance cover damage from items left in the car?
Standard rental insurance in Dubai typically covers accidents and third-party liability. Damage caused by negligence including leaving flammable items inside a hot vehicle is generally not covered. Always review your rental agreement and check what your insurance includes before driving.
What's the best way to keep a hired car cool in Dubai summer?
Park in shade, use a windshield sunshade, and allow the AC to run and circulate air for 60–90 seconds before getting in after the car has been parked in the sun. Regular tyre pressure checks and keeping the coolant topped up also help the vehicle manage summer heat more effectively.
Can heat damage the car itself when it's parked?
Yes. Prolonged extreme heat affects dashboards (cracking and warping), seat materials, the battery, and interior plastic components. In a rented vehicle, cosmetic or mechanical damage that occurs during the rental period is typically the renter's responsibility.
Conclusion
Dubai summer heat isn't just an inconvenience — it's a genuine hazard for anything left inside a parked car. Temperatures that regularly push past 45°C outside translate to 80°C or more inside a closed vehicle. At those temperatures, lighters ignite, aerosols rupture, medications lose effectiveness, electronics degrade, and ordinary objects become fire risks.
The solution is simple: don't leave these things behind. Build the habit of clearing your car before you park it, just as you would lock the doors. It protects you, it protects the vehicle, and it protects you from unexpected costs if something goes wrong with a hired car.
