Attica is warmer during the night and Andalusia is warmer during the day, that´s the most relevant fact, because the averages are not even one degree apart.
I was shocked that the difference between the top 12 warmest yearly mean in Europe were also such tiny...for example, Faro was only 1.98ºC colder than Palaiochora..and Faro was in 11th place while Palaiochora got the first..
Yes, I agree with you. I did said the same thing, sometime ago.
Faro, with it´s local fresh cape type of climate, getting up to the 11 th place is laughable... I wonder about what would happen if the warm regions start to be studied in Algarve, let alone the Guadiana Valley, Tagus valley, Guadalquivir valley, etc...
One important note: this small home made contest, is only about some cities, it doesn´t give an idea about where are the warmest places and how warm it are. And for me, this would be the ultimate challenge, all the rest is rubbish, just to fulfill the ego of someone. On that « challenge» that you presented, some cities are chosen by people, but data isn´t based on averages and these figures are only based on small samples. lol This simply put; 1, 2 or 3 years data, can be only interesting, not really important climatically, to define the warmest areas. Also this data can downgrade unfairly other countries, simply because it haven´t the same weather coverage, on it´s warmest areas. If you check the altitude and the weather station positions, between the countries, you´ll easily notice, the bias behind all this... Nevertheless, is a bit interesting, to understand that even a locally fresh place, can get so close to other ones, well known for being locally «warm».
Seville getting so close to Crete´s Palaiochora, is also funny in my opinion.
See the differences between the positions of these 2 cities and you´ll understand why.
So my conclusion about this small data sample, is that, though interesting isn´t solid/ complete enough to make a serious scientific climatological resume about it.
