Back in the days, July was the factory closing month here in Sweden. Lots of functions needed to keep it open.
It must be safe and others hear your cries for help if the worst should happen.
Changed in the late 1980's when production had to go on except for national holidays.
The weather knew it too. Rain pouring down when leaving for vacation or next Monday.
The sun returned when back to work again. A must to travel south like Spain, Italy, Greece etc.
