Winter and the varoa mite

[itma]

Latitudes (nearest degree)
London 51
Aberdeen 57
Helsinki 60

Average Low/High September temperatures (ditto: source worldweatheronline.com)
London 13 / 20
Aberdeen 9 / 15
Helsinki 7 / 16

Never mind Helsinki; Aberdeen beekeeping is going to be a very different experience from mine. I bet the September flows are WILDLY different.

Interestingly, you have selected September and the heat island of London for comparison.

Your source gives these average figures for October (Jeffree's brood minimum)
Canterbury 3/15
Aberdeen 7/12
Helsinki 3/9
which seems to lend some support to my contention that October in "far North" Aberdeen isn't significantly colder than Kent …

I was just mAking the point that the runup to that brood minimum target would be different. And I was amused by the Finland reference. Again, I guess your ivy flows would be different from Aberdeen. But we agree on the basic points and I will post ( prob in the apiary thread) what I find.
