Depends how ambient ambient is. Recently on a cold bright day with snow on
the ground I took the lid off a double brood chamber colony expecting to see a
tight cluster in the bottom box.  Instead I found about 50 or so bees working
in the top box, as surprised to see me as I was them.

While it was close to freezing outside, and the hive has an open mesh floor
with a foot drop beneath it, there must have bees enough solar radiation
heating the box to allow the bees to break cluster and forage within the hive.
