Abisko is, what, 450 m ASL?
Interesting they have reached almost 33C.
Wouldn't call winters warm though.

I'm currently taking requests for Swedish and Finnish data and weatherboxes! Kilpisjärvi
Abisko
Lysekil or a somewhere along the coast north of Lysekil
There are no coastal stations active. Nordkoster has a 2002-2015 climate box already though en.wikipedia.org/wiki/Koster_Islands#ClimateThe bus station Hud had a station that was active 1997-2016. For 2002-2016, January and July were 1.2/-1.2/-3.5 & 22.3/17.6/13.0 respectively, and for 1997-2016, they were 1.2/-1.1/-3.5 & 21.8/17.1/12.4 |

 a station in finnish lapland, on the border with norway. this might be the most isolated weather station in finland. |

I know it’s a short time period and these are unusually warm and dry years but thought it would be interesting. Here’s Whiteface Mountain in the Adirondacks at 4865’.  Highest elevation station in NY, sadly it was only open 9 years. It recorded a 34 f high on June 21, 1940 and had a 37 f high in August. Averaged a snow pack from late September to early June, and recorded at least a trace of snow in every month. |

That's racist! Think the outrage if somebody would call a peak Blackface Mountain!

To refresh my data analysis skills I played around with Frankfurt Airport's mean temperature data set (1949-2018). I tried two smoothing methods for the monthly data. At first Loess Regression with a 50 % smoothing span (red graph) and then moving averages with a ten year span (black circles). I placed the dots in the middle of each timespan, hence there are dots missing for the first and last five years. All in all there is a warming trend detectable for each month, only February shows a recent cooling tendency.    |

Compared the Sundsvall-Råsta station to the airport station for 2002-2015. January averages: -2.0/-7.4 vs -2.6/-10.6 and July averages: 21.5/12.4 vs 21.5/11.8 Quite the difference lol Hardly an ideal placement for a station though  . According to satellite image rulers, it's 4m and 6m to each road lane. Looks closer on the image. |

I was curious about how much Louisville is affected by UHI, so I made a chart for both the airport and the NWS office just over 5 miles further out from the city. It looks like the general climate of the Louisville area is indeed closer to Lexington than I had previously thought (but still slightly warmer). The difference in precipitation days is particularly surprising, unless there was an unknown recording error for one.   |

Stavanger
I know the climate of Stavanger, I have spent some time there, even lived there. I have used Stavanger as location in my weather summaries, representing SW Norway, so wanted to do some research about that location.
Averages: I did not want to use the old 1961-90 normals, as they don't represent the current climate very well, and certainly not future climate. No updated normals available, so I used Weatheronline's climate robot, which only had data for 2011-2018, 8 years, and it isn't 100 % accurate but fairly good.
Observation period: The Våland station is in the city itself, on a little hill, while most of the city is at lower elevation. Started recording in 1882 - only precipitation. Temperature seems to be recorded since ca 1927, but only a little data in database that early, guessing it is written notes and only interesting temps/records are digitalized from the first years, like the record low of Sep and Oct. From 1943 good temperature data untill Jan 1988. Then discontinued, operating again from Aug 2008 - present.
Extremes: The all-time low of -17.8°C is from the famous cold wave in Jan 1987. The coldest low in any other month is -14.1°C in Jan 1979 - 3.7°C difference! Three of the all-time highs are from 2018 - Apr, May, Jul. 8 of the 12 record highs are from after 2000. Only one of the record low is after 2000 - Nov from 2010.
Sunshine: 1961-87. More recent years have been sunnier in Scandinavia, partly because of less aerosol pollution so that low sun angles are more likely to cross the threshold and be recorded as sunhrs, thus more recent years should be ~ 1,600 sunhrs.
As can be seen there is som seasonal lag, unsurprisingly. A mild climate for Scandinavia. This is probably the worst city in Norway for snow lovers, as only NW will produce snow, and even that might be too mild as there are some temperate sea to cross. Lows going in the Skagerak can give large snowfall on the south coast of Norway, but not in Stavanger, it just too far north and shielded from that SE precip. People wanting to ski drive to Sirdal, an inland mountain valley 1 hr drive away, or take the boat inland to Sauda.

Why use weatheronline when you have access to eklima? Stavanger airport had full data from 1991-2018. Here you go.   And the sunshine is only available until January 1981 |

Thanks, but these averages are for Våland, not the airport.

Thanks, but these averages are for Våland, not the airport. Indeed, but 8 year averages are pretty useless, and the airport had full data  |

Stavanger has different geography than the airport.

Stavanger has different geography than the airport. What's up with Eklima having such shitty data percentage. 9/10 of all stations saying they've been active for the last 30 years have only like 10% data available. |

Calculating manually include precipitation and snow will take too much time so I just did the temperatures.   |

Stockholm city airport vs UHI station   Bromma airport seems to be in a slight depression. Probably not enough to call it a frost hollow though.  |

Now with 100% legit data. Turku Airport 1991-2002, Turku Artukainen 2003-2017:
Comparison with 81-10 normals:
Jan: +1.0 Feb: +0.9 Mar: +0.7 Apr: +0.4 May: +0.3 June: +0.2 July: +0.6 Aug: +0.8 Sep: +0.8 Oct: +0.1 Nov: +0.8 Dec: +1.4 Precipitation: -35mm (-0.5%)
Turku maded superior to same latitude Sweden jajaja  |
