Weather-wise, it is and has been mostly gray, e.g. overcast skies over Stockholm - with some rain here and there. Typical late autumn weather in Scandinavia, with the difference that it has been exceptionally mild in the past 8+ days (in average +4.5°C above normal temperatures for the time of 1-8th Nov 2025). I am sure this will get ironed out over time, as we expect colder weather. Or at least some colder periods, between milder ones.

Yet like so many times before, the weather prognosis centers around the world, predict (calculate according to "models") colder weather - and then days later on, the colder development seems to be more of temporarily nature instead. It is of course, never written in stone, no matter what an app, or prognosis of any kind states in letters.

Nature is endlessly more sophisticated then that. Thanks God.

Hurricane Melissa - but it started already earlier

The initiation of very mild weather, was due to (but not solely) because of the ex-Hurricane "Melissa" which turned into an ordinary low pressure area on approach towards Europe, e.g. Scandinavia. With it followed / continued an increased inflow of very mild air. (In Sweden up to 16.5°C where registered the other day). This inflow was then was upheld through several more low pressure areas going in the same direction, pulling up mild air from the Atlantic.

However the general trend in the inflow of mild air through many low pressure areas towards Scandinavia, started already around 20-21 Oct 2025.

You can see that in the temperature curve (MAX vs MIN) for Stockholm City below. Especially the nights where very mild, exceeding at times even 10°C at night.

Unusual ? No, not at all. Not really.

It happens quite often in Scandinavia. We have had exceptional high temperatures registered in November as recent as Nov 2022, Nov 2020, Nov 1968 but also in Nov 1899 (!) with MAX temperatures between 17-18°C.

If i recall correctly the all time high November record in Sweden was 18.4°C measured in Gladhammar on 6 Nov 2020.

What I find slightly remarkable is that we (in the center of Stockholm City) still haven't had any frost. Neither have I seen any here in the inner outskirts of Stockholm this far.

Neither snowflakes nor frost.

But it is on the way quite soon. Or so they tell us.

Subway Driving Implications

Somewhere around Friday 14 Nov, frost should come into play.

It also will make driving the subway more tricky in the morning, sliding ferociously and slowing down the train, due to the software inhibiting acceleration (in order to protect the wheels from getting plates on the wheels (= plates which occur due to locked up wheels when you break ;

The Wheels then slide along the rail while going into locked mode - which grinds plates into the round wheel shape. This then makes loud booming sounds, every time the plat portion of the wheel meets the rail. This in return can damage the rail / break the rail - especially in cold weather, when metal gets more brittle)

So, all that - in combination with excessive many speed limits we have in many sections of the Green Line, makes the demand of punctuality (with now decreased margins with the new company "Connecting Stockholm) an impossibility to be achieved.

The first trains out in the morning, are the most tricky ones, because frost makes the rail super slippery, slowing down everything.

So. There is that.

When realty meets stupid office desk agreements. The latter created out of very different intentions as well greed ("To have one's cake and eat it too").
