Is it harder to drill holes in metal when the metal is cold?

For some reason I think so.

I have a few holes to drill in 1/8 or 3/64" steel, outside, and it's
about 30 degrees most days lately. They are going to be awkward to
drill in the first place, so I don't want it to be harder to do, and I
can delay it to 70 degree weather.

That's no big deal but now it's more important to me as an academic
question.
Hi,
B4 asking, why don't you try and tell us?
