Doesn’t matter what time the sun rises for me, I’m going to have to wake up much earlier than the sunrise so that I can work productively outside for a few hours before it becomes unbearably hot. I’d rather not have to wake up at 4am because some wanker working in an office wants breakfast at sunrise. Waking up along with or after the sun rises is simply not an option for many people. That’s the daylight they are saving, productive and less dangerous working conditions for people working outside in the south and southwest. Work culture can be adapted to when you want to work, I can’t change when the sun starts beating down and makes it dangerous to work.
It doesn’t cool off in the evenings because of humidity.
