How many all-time highs have your place recorded recently?

Norrköping:

Warmest ever May (2018) 22.5/7.9 = 15.8°C for 24-hour mean and 15.2°C for conventional mean.
Warmest ever July (2018) 28.5/15.2 = 21.8°C for 24-hour mean and 21.9°C for conventional mean.
Warmest ever May and July max temp averages in 2018 as well.
Sweden's warmest temperature from the last week of August ever = (26 August 2016, didn't occur for Nyköping that day but saw a 24.5°C temperature reading at my thermometre at 10.30 pm as the hot air drew in after sunset, so it was stable 24 all that day here from dawn to beyond dusk).
Max October temperature (2018) = 23.0°C (that unfortunately didn't occur for Nyköping that day).

Going back five years you can find 15.2°C as the November record from 2014.

Might have missed something, but I don't think I have.

You're not referring to SMHI's means, right? Because those are pretty bogus.

They are by no means 24h means. They're calculated in a really weird and complicated way with different calculations depending on what month it is. Don't refer to it as 24h means. They can differentiate from 24h means just as much as (x+y)/2 can.

Rovaniemi Airport since 1951.

The data available to me is monthly and annual SMHI-mean and record temperatures. Records are only since 1901, so some may have been warmer earlier. Some records have been broken twice, like for example July 2014 as well as 2018. I did not count these.

Timeframe A:
Warmest May temperature of 27.8'C in 2018 (I'll count it because Nidaros did, even though it's more than 12 months ago)
Warmest July mean 2018 of 19.9'C

Timeframe B:
COLDEST September temperature of -8.5'C in 2014
Warmest July temperature of 32.3'C in 2014

Timeframe C:
Warmest March mean 2014 of 1.1'C
Warmest March temperature 2007 of 14.2'C
Warmest May mean 2013 of 11.2'C

Warmest (since 1901, we have an old 33.5'C from the 1800's) June temp of 30.1'C from 2008
COLDEST July temperature of 1.1'C in 2008
Warmest August mean of 17.6'C in 2006
Warmest November mean of 3.3'C in 2011
Warmest December temperature of 9.3'C in 2013



Not as many records as in some other places. We even broke a few cold records relatively recently.
