Canada?

It was 32C yesterday. Our winters will certainly get far below 32F. Well into the negatives in fact.

That's not that unusual. In the Midwest it can go from 0f in the winter to 100f in the summer, which is beyond this range anyway. 30c is about 86f which is nice weather to me. I wish we only peaked at 30c. So yeah, 30f to 30c would be just dandy

american continent has more temp range than continental europe does.

except the west coast, which has a more mild climate with a lower temp range.

climate change is causing europe and the west coast to become see the more varied temps than the rest of the north american typically sees.

I grew up in the American Midwest. Average Jan low 17F, Average July high 89F (-8C to 31C). Those are averages, with plenty of days well outside that range especially on the cold end. Summer were not too bad. Now I live in hell and it gets over 35C every day for months on end and it's a wet miserable heat.

Sounds about right for e.g. Germany ~15 years ago. Does this range seem odd to you because it is too wide or too narrow?

Sounds like somewhere near an ocean tbh
