Comment on Amazon's drone delivery program is the joke it always sounded like.

  They’re using a very dated design because the FAA moves extremely slowly. The size, weight, and wide-scale intended use of them puts the drones in an aircraft category that comes with a lot of paperwork and stipulations.

    In this case I would consider that a good thing. The day drone delivery because common will be a very noisy day.

    Ew… Bureaucracy.

  Flying with a payload requires a lot more lift which goes down as temps go up, plus it could be just the heating of the motors under load that have a certain limit before they tend to fail.

  Maybe just a safety precaution for lipo batteries? Given the potential hazard of bursting into flame near or on a house

    The primary factor is probably air density. Hot air is less dense than cold air. Humid air is less dense than dry air. High altitude air is less dense than low altitude. Hot, humid, and high, an aircraft’s available payload could be a small fraction of its cold, dry, and sea level capacity.

      The difference in air density from 0°C to 45°C is only around 20%. I can't imagine that would be enough to cause problems, assuming the drones have a decent safety margin. I think it's more likely it's a safety precaution for the electronics.
