What's up with all the Swedish locations on Wikipedia only using 15 years of data?
The Swedish Met Office hasn't released normals since 1961-90, so wikipedia users have decided to do their own. Why they chose 2002 is beyond me, but the 2000's has been the warmest there is. I have no idea why they decided to ignore the period of 1991 to 2001.

SMHI has only given out 2002 and later. Very odd, but at least it's a much more useful figure than that of 1961-1990...
Either way, between 1983 and 2013, Visby averaged approximately 1990h of sunshine, judging by this picture posted by SMHI:
So there isn't a place in northern Europe that sees 2000+ hours?
No station has recorded 2000h for the 1981-2010 period, but there are a few that have over 2000h for the last 30 year period (Visby gets about 2040h), and Holmön, Sweden could possibly have got over 2000h for the 1981-2010 period had they been recording sunshine.
Visby and Hoburg will most likely do for 1991-2020.
Having said that, as for Wiki and 15 years of data most station's official data don't even carry avg highs and lows in the official codes for the normals, just means for 1961-1990 so even if they'd been utilized there'd be zero and nada weatherboxes for most places. The monthly statistics starting from 2002 are good in that they publish highs, lows, actual temp/24h means and all good and useful stuff.

Very interesting.
Question is: Why are all the Swedish locations getting more sunhours compared to earlier decades? The last few years indicate that the same is happening in Norway, no surpise off course as we are the neighbours next door.
Arethere less Lows bringing clouds?
Is the subtropic High moving ever slightly northwards in summer?
Are there less aerosols in the air now? Less pollution in the air?
According to Lommaren, Visby increased from 1882 sunhours to 2123 sunhours if 1961-90 is compared with 2002-2015, that is 13 % increase!
2123 sunhours correspond to 2441 sunhours if the US standard were to be used, inflating sunhours according to what I have seen on this forum.
Using the now ancient 1961-90, Kritiansand in Norway averaged 1777 sunhours.
If Kristiansand increased by 13 % that would give 2008 sunhours, corresponding to 2309 hours using the US standard.
