Strikingly warm in Sweden as well. Geothermal heat pump does work a few hours per day, anyway. It drops far below 10 degrees celsius at night and my house is not modern enough to manage comfortable temperature with only waste energy as source.
Chiming in from Poland. There have been a few cold nights in the last week or two, but otherwise it's autumn-level warm. Today in particular was unexpectedly warm, early summer levels.
Slovakia, we didn't start heating yet, a few years ago that would be unthinkable. Looking at the forecast, we won't be heating for at least another 10 days.
At least the energy crisis has been averted for the first month of the autumn season in Europe and the outlook looks promising going into the second month esp for households in light of rising costs and soaring inflation.
Good right now in the energy crisis, not so good long-term when higher temperatures won't be matched by more rain, which they probably won't, and we will slowly turn into a savannah.
