Why an August truck ruins things a January truck would not
A closed box truck in UAE summer sun is an oven: ambient 45C plus solar gain routinely pushes the cargo space past 60C, which explains a specific list of failures. Candles, lipstick and chocolate liquefy. Aerosols build pressure toward their burst limits. Flat-pack adhesives soften, so a wardrobe that survives the carry fails at the joints a week later. Laptop batteries sit close to their maximum rated storage temperature.
The subtler mechanism is condensation. Your flat is at 22C and dry; coastal August air is 40C with a dew point above 30C, so water condenses on any chilled TV or mirror, which then gets sealed in plastic film and left damp for hours. Good crews let cold items warm up first, or wrap in breathable blankets. In summer: take the earliest slot, load electronics last, carry medicines and batteries in your own car, and let electronics acclimatise before powering on.
