I would like to know how many frost days do others European countries get, especially comparing the Iberian peninsula to the another two peninsulas that make up southern Europe.

There is a Spanish weather website that are working to find the coldest places in Spain, which is called "polos del frío". In fact, there are some places located in few isolated mountain valleys that work very well when atmosphere creates the temperature inversion at clear nights.
Most of these mountain valleys are located in the northern half of Iberian peninsula.

Some of them even get frost in summer, especially these that are located quite far away to the Mediterranean coast, which is pretty spectacular considering the latitude of the Iberian peninsula.
I was wondering if another cold valleys located in mountain areas of central and northern Europe, such as the Scottish Highlands, the Belgian Ardennes hills or the Sudetes mountains can get freezing in summer months.

On the other hand, there are some cold valleys located in pre-coastal areas of Mediterranean coast that work very well when temperature inversions happens, not in summer but the rest of the year, such as some places located in Catalonian Prelitoral mountain range at Tarragona province.

Well, now I show you a list fields containing some record cold nights from "polos del frío" weather website.

I don't have a database like yours or much mountain data, but here is a map of Britain showing frost days. Outside Scottish mountain valleys very few places average below-freezing lows even in the coldest month, so we are really very tame.

Re. the Scottish Highlands, parts of it can and do get summer frosts, but not that many:



I looked up Braemar, and it gets 101.7 frosts a year by the 1981-2010 averages at 339 metres asl - I don't know if that is the most of any official station. It gets 0.5 in June, 0.0 in July and 0.2 in August.

Italy:

Mountainous areas
Resia, Trentino-Alto Adige (1.430 m): 162
Dobbiaco, Trentino-Alto Adige (1.230 m): 162
Tarvisio, Friuli-Venezia Giulia (780 m): 128

Plain areas/valleys
Malpensa, Lombardy: 108
Bolzano, Trentino-Alto Adige: 98
Novara, Piedmont: 89
Turin, Piedmont: 83
Brescia, Lombardy: 75

Data from 1971-2000. Also many other cities and towns surely get a large number of air frosts (I think more than 80-90) but I can't find official data for these: Aosta, Cuneo, Sondrio, Trento, Vipiteno, Bressanone, Belluno, Asti, Alessandria, Vercelli, Avezzano, and many small towns in the Alps and the Apennines, especially in Abruzzo.
Not to mention famous ski resorts like Cortina d'Ampezzo, Courmayeur, Breuil-Cervinia, Sestriere, Bormio, Livigno, Madonna di Campiglio, Abetone, located at altitudes of 1.400-2.000 metres.

Yes it gets to freezing in like July in braemar.

And I would say maybe they get an average of 20 ice days a year. But the coldest in europe would be north norway.

this location is one of the safest bets for july-frost in sweden. at least below 500 meters.

in lapland its actually fairly uncommon with july-frosts. last year karesuando in extreme northern sweden recorded its first july-frost since 1949.

There must be some isolated uninhabited areas in Finland, Sweden and Norway that should broken the coldest places of Spain.
However, the Iberian peninsula is largely mountanious, so that's why there are some few valleys well dispossed towards strong temperature inversion in clear calm nights, even in summer, in spite of more than 90% of our territory is warm to northern Europeans' climate patterns all year round.

What about southern Apennines and Sicily?
