Just a reminder that all beekeeping is local, and it is best to know the
weather in the location that uses different equipment. Many parts of
Europe are located much further north than much of the US, but enjoy
fairly mild winters and have temps that are closer to Maryland than
upper NY state or the Dakotas. Many parts of Sweden are warmer than
parts of Maine, including one city close the the Arctic circle, all
because they are intelligent and have their larger cities close to
water and the warm Gulf Stream.

Even in North America you can have exceptional differences  - Maine vs
Washington State. Upper NY State is cold, often colder than southern
Maine, so I buy a lot of trees from that area knowing that if they
survive there I have a chance here. So I would trust Lloyds observations
on wintering more than those from others, since our climates are close
in temperature and other environmental factors.
