6 O'Clock Hot

6 o'clock hot is where the temperature is so high, you can't do anything until 6:00pm in the evening - you just want to lay low and as close to air conditioning as possible!

Cedric The Entertainer often uses this expression to describe the Southern states of the USA.

Dave: "It's pretty warm, ain't it?"
Mike: "Sure is - it's 6 o'clock hot"
