Latitude is a poor point of comparison here, North America tends to be substantially colder than Europe at the same latitude.
Or concretely Niagara Falls goes from an average low of -6.44 C in February to 21.0 C in July. Barcelona an average low of 4 C in January to 20.2 C in August (according to the internet).
But yes, it's warmer than Finland, just cold enough to see something of a freeze that cycle.
A couple days of -6 is probably a lot easier. Its probably still economical enough to heat the equipment on the days below 0. I imagine having a couple months of -20 is a bit different.
