Extremely cold when you step outside you mean
Incorrect.
Way off, in fact.
Let me explain it in language you understand: Ireland sits at the edge of the north Atlantic, the ocean and the polar regions clash with the trends arriving from further south from the gulf of Mexico. This causes all sorts of weather out at sea and when it travels east, it batters the fuck out of Ire;land and the rain never stops. That humidity is what makes you really shiver - the kind of cold that it doesn't matter what you wear: it gets into your bones and makes you shiver and feel severely cold even indoors. It sucks.
Whereas in Finland, humidity isn't a factor pretty much at all. This means we can walk out into minus thirty degrees dressed pretty much like you are (except our clothes are bigger and furrier) but we don't get cold through and through: we leave our babies outside for naps in the sunlight, even if it is minus ten. Minus five? No big deal really. Minus ten and heavy snows and winds? You can still set your watch by the trams and buses.
In Urrland?
You're left standing at a bus stop in some kip of an area surrounded by rubbish and empties, the bushes clogged with plastic bags, the gutters spilling over with mucky rain water, the wind hitting you from every angle, and every bus you wait for comes late. Complain about it and the driver will fuck you off his bus. Get on? Don't sit upstairs what ever you do - and if you have to, do NOT look anybody in the eye.
Today it's two degrees above. The last of the ice is melting and many streets have been washed and brushed clean of months of hiekka (grit) laid for pedestrians. The thoroughfares are spotless. In a week all the hiekka will have been returned to its storage boxes on the major street corners: the hiekka boxes are then used for temporary seating in summertime. Mental, eh?
So in another week or two I'll be trading my winter wardrobe for my summer wardrobe: this is made easy by the fact that my apartment includes a four square meter steel cage in the basement for me to store things in room temperature. The other one in the attic is cold. So items of furniture, appliances, etc are stored there.
But you'll still be taking an umbrella with you to cover your hoodie until around late July, when you'll get a four or five day stint of 25 degrees plus, about which you'll start complaining of the heat discomfort after the second day of warm temperatures. As soon as it arrives it'll be gone again, and you'll be back to the miserable grey skies and heavy clouds promising even more heavy rain.
That makes me happy.
I have no interest in foreigners "integrating"
Good man.
The lads down on Mount Street will be relieved to hear of it, I'm sure.
They can focus on what they do best: taking you for a ride in your own home town.
