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.

It's actually easier, because the molecules are moving more slowly. You
don't want them running around like lunatics, jumping out of the way of
the drill. However, wearing mittens while drilling does make it a little
harder.
