35-90 degrees F. Cover if it's going to be below freezing at night. Concrete will make it's on heat the first couple of days as it's curing. You can walk on it in a few hours. Give it a couple of days, and it'll be good to go for your bird pole.
A note on purple martins: Once they move in, you won't have any mosquitoes, but everything you own will be covered in bird chit.
