European here. Like me, many people from the poorer european countries don't have any place to go on vacations in august. Everything is expensive and there's always a rush to booking. For someone who doesn't have a "family summer house" and can't afford to rent a place in august, mandatory august vacations (like it's usual here) is just a waste of vacations. Too hot and no place cool to go. Also, august is typically the month where everything is flooded with small children. If you're not too fond of that either, then august is really the worst month to be on vacations. ALSO, it's lovely to work in august, because usually your workplace has AC and most of your colleagues are hundreds of kms away, trying to buy a melted ice-cream for 40min in a crowded beach.
