The afternoon is not usable for heavy work
Between June and September, Marrakech afternoons regularly pass forty degrees, and the heat radiating off stone and asphalt in the late afternoon makes the effective temperature higher still.
Carrying furniture up a staircase in those conditions is not simply unpleasant. It is a genuine safety question, it slows the work to a fraction of the morning's pace, and it raises the chance of something being dropped. So the working assumption in summer is that the heavy carrying happens between first light and midday, and the afternoon is for the parts that do not involve lifting.
A closed truck is an oven
The temperature inside a parked, closed vehicle in August in Marrakech climbs far above the temperature outside it. Anything left in there for hours is not simply warm; it is being cooked.
Candles and anything wax-based will not survive. Vinyl records warp. Electronics and screens sit outside their rated storage range. Some adhesives soften, which is what quietly opens the joints on furniture and lifts veneers. Wooden instruments go out of tune and, occasionally, out of shape.
The answer is a short dwell time rather than clever packing. Load, drive, unload. Belongings should not spend a summer afternoon waiting in a vehicle, and a schedule that has them doing so has been planned badly.
The medina compounds all of it
Inside the walls, the load travels the final stretch by handcart through alleys that trap heat and hold it. There is no shade to wait in and no shortcut to shorten the distance.
A medina move in August is therefore the clearest case for starting at dawn. The same job that takes a comfortable morning in April becomes genuinely punishing by ten o'clock in August, and the only variable you control is what time you begin.
Water, shade and pace are not optional
A crew working in this heat needs water available continuously, not at breaks, and needs to work at a pace that accounts for the conditions. That is a professional obligation, and it is also simple self-interest: a tired crew damages things.
If a company quotes you an August move in Marrakech on the same timings as a November one, that tells you something about how the day is going to go.
The shoulder months are genuinely better
If your dates have any flexibility at all, April, May, October and November are the comfortable months in Marrakech, and moving in them is easier on everyone and everything.
That is not always a choice — leases end when they end and postings start when they start. But where there is a week of latitude, using it to step outside the peak of the summer is the single easiest improvement you can make to a Marrakech move.
