I had a giggle at "very cold" + "-20°C"Re. cold temperatures in France :
France has 3 different climates :
- Mediterranean climate (hot summers - mild winters)
- Continental climate (hot summers - cold winters)
- Oceanic climate (temperate climate)
Of course, this can be variable depending on the geography :
- In montains (Alps, Pyrennees, Jura), the winters are very cold. One place in Jura is known as the "little Siberia" (up to - 20 C). But the summers can be very hot too.
- In Auvergne (montains Massif Central), winters are very cold too.
- In Berry, they are at the limit beween Oceanic (temperate, moderate) and Continental (colder winters - warmer summers). I would say that the temperatures in winter can reach - 8 C (sometimes).
BUT : Keep in mind that the feeling can change with the humidity level in the air (dampness) too. In a dry air (the Alps or Pyrenees for ex), negative temperatures are easier to bear than a good 7 degrees Celsius in a damp region.
And Berry region is very damp...
Our Canadian winters can easily reach -30°C. And then feel worse with a wind chill. But, our houses are very well insulated, with central heat. I'm always so surprised at the lack of insulation in some houses I see in the UK and France. But then, the climate is milder there (in some places)
