Is it hot all day in Las Vegas or do you get a few hours in the morning when its comfortable?

Only in the summer. This a.m. when I got up at 7am it was 39 outside. So yes it does cool down. It is winter time. Did you think it hot in the winter too?? Research the weather for here.....

During the winter months water is freezing on the lawns and it gets into the 50's during the heat of the day. In the summer months it a whole different thing. You can fry an egg on the sidewalk during the day. Even the nights are hot. The coolest part of the day is just before sun rise. It does heat up fast once the sun comes up.

What time of the month are you going? If your going from now until feb its around 60F during the day and it gets to around 40F at night.. I was in vegas last month and was ok with wearing a sweather and shorts around town..

summer time. you are correct in your assessment. After 7 -8 p.m. depending on the month, it gets comfortable again.

Summer is our hot season between noon and 6pm, the rest of the time it is wonderful

Summer is over. Soon it will be freezing cold there.
