Hey Luth,
it's very similar over here. We're up for about 20°C. This feels scary with the autumnally short days and low sun. But even scarier were the 20°C Munich experienced last December!
They say that the climate change is confusing air streams. That lead to cold and long up here winters recently even though the average world temperature was higher than ever, and these late warm days may be related to that, too. I mean, strange end extreme is nothing new at all, but the exceptions of yore are becoming the rules of today, and that is strange and frightening.
Cheers, anyway!
Markus
