Last August I compiled a mostly accurate record of the warmest temperatures in each day of the year in Scotland. I updated it last night and since then there have been a few new additions: 

10 Nov 18.9 Kinloss 2022

11 Nov 19.1 Lossiemouth 2022

12 Nov 16.8 Dunbar 2022

13 Nov 17.5 Achiltibuie, Poolewe, Port Henderson 2022

10 Jun 29.8 Auchincruive 2023

12 Jun 30.7 Threave 2023

It seems likely today saw a new daily record. Yesterday’s temperature in Threave was a new record June record for the station and I believe Dumfries and Galloway. Only two dates in the calendar have recorded a higher temperature earlier than the 12th June.

Water scarcity and drought information for Scotland

This thread could be used for unusual weather events such as severe thunderstorms/hail storms/tornadoes, unseasonal snow/freezing rain, flooding/storm surge/landslide, wildfires. 
 

As a result of the recent dry weather we’ve seen Loch Ness drop to the lowest level in decades and the wildfire in nearby Cannich is believed to be the largest on record in the UK.

The famous loch along with the River Ness have hit record low water marks.

Firefighters say flames burned through a 30 sq mile area near Cannich but it is now under control.

[A Winter's Tale]

June 2023 was the warmest on record in Scotland with a mean temperature of 14.3C (bearing the previous record of 13.4C in 1940).

[Kirkcaldy Weather]

I've recently discussed how abnormal the pattern that's unfolding through weeks 1 into 2 of July across the UK, Iceland, Scandinavia and into Europe is

Absolute bullseye for pattern links with MJO

Buckle up everybody it's the turn of the UK to experience abnormal weather.

Just how abnormal will this pattern be?

Beginning with the 850hpa temps these will WIDELY be AT LEAST 5 DEGREES BELOW AVG  

Might be a small window for 10-12 DEGREES BELOW AVG around Orkney + Shetland

For surface temperatures I'm expecting AT LEAST 1.5C BELOW AVG - say 4C BELOW AVG in the UK + Ireland with similar across Scandinavia though they might average slightly colder overall 

 

I have studied the coldest EVER Max temps for UK + Ireland in July which was 1978

  

Now match this setup with 1978

I wish the Met Office made it easily accessible for daily temp and other wx records, the NWS in America is a thousand times easier and simple for that aspect

 

 

Incredible seeing 0C and -2C 850hpa temperatures in Scotland during July

500hpa temps equally mental 

I'd wager these are high on the list of coldest 850hpa temperatures into Scotland for July ever recorded, I really would be interested to get more detailed records but not sure if there are any accessible to the public @A Winter's Tale @Jo Farrow

Great stat work @A Winter's Tale

I'm thinking a fair shot somewhere sets a record High minimum tonight

Record currently sits at September 18.7C 29 September 2011 Achnagart (Ross & Cromarty)

[A Winter's Tale]

New station records for September maxima today: 

28.8 Glasgow Bishopton (equals date record at Charterhall in 2021)

28.5 Aviemore 

28.3 Aboyne

28.2 Drumalbin

A truly exceptional period of weather. 

[A Winter's Tale]

A couple of other stations set new records for September maxima. 
 

26.8 Leuchars

25.3 Inverbervie 

An impressive number of weather stations have set new records.

29.3 Kinloss (7 Sep)

28.8 Glasgow Bishopton (8 Sep)

28.7 Lossiemouth (7 Sep)

28.5 Aviemore (8 Sep)

20.0 Fair Isle (8 Sep)

19.3 Aonach Mor (8 Sep)

I think Kinlochewe, Achnagart, Fyvie Castle and Tyndrum set new records aswell. 

Some stations were not far off all time record maxima: Kirkwall (24.8), Loch Glascarnoch (28.0).

[A Winter's Tale]

A temperature of 19.2C has been recorded at Kinlochewe. This is a record winter temperature for Scotland and a record January temperature for the UK. 

[Norrance]

  @A Winter's Tale

yep. From an official site too. Provisional record for now but looks odds on to be correct

Edited January 28 by Norrance

[Methuselah]

That's an amazing temp, guys. . . I was in the NW Highlands in 1989; it was about 14C up there and only 7C in SE England. Are we seeing a turbo-charged version of 1989? 

[Jo Farrow]

19.6C in the end for Kinlochewe, but manual daily data from Achfary has come in with 19.9C on the 28th . Both provisional.

Dr Eddy 'Weather' Graham https://twitter.com/eddy_weather

@eddy_weather  Lots of talk re: föhn yest, but the standard setup alone cannot explain highs of 19-20C in NW Highlands - no operational met model picked it up either (resolution issue?). Dry descent of air from ~1500-2000m in huge mtn waves is likely culprit IMHO, given coincident fierce wind.

  @Jo Farrow

Doesn't Achfary already hold the December record high?

[dryfie]

Achfary does indeed, 28/12/2019 IIRC.  It's the site office for the Duke of Westminster's estate office in the village.  The site isn't automatic like most reports we receive.  The readings are taken manually at 0900 each day, hence the delay in the report being received.  Reckon they'll be painting another phone box as celebration (there's one of our members who will know what I mean).

[dryfie]

A note of caution…has there been anything official from Met?  This may just be an unofficial report from somebody’s Met.are.us toy weather station.

[dryfie]

Now confirmed as official.

I omitted some date records which didn’t seem plausible or were recorded at a station (such as Dawyck Botanic Gardens) with questionable readings. 

The date records omitted include:

25 May 4.7* Dawyck Botanic Garden 2022

5 Jul 7.0* Faskally 2023

11 Jul 8.9* Faskally 2023

5 Oct 3.1* Durris 2022

18 Oct 1.8* Dawyck Botanic Garden 2022

7 Dec -11.4* Dawyck Botanic Garden 2010

13 Dec -6.0* Dawyck Botanic Garden 2022

14 Dec -8.6* Dawyck Botanic Garden 2022

I’ve excluded mountain stations such as Cairngorm Summit. 

I am not 100% certain about the accuracy of all the date records but I’m confident the majority are valid.

 A Winter's Tale Many thanks for putting me right about Dawyck.  I was always under the impression that the extremes reported there were due to the valley location with trees and mountains to the south shielding a lot of the sun.  You are presumably aware of the location, so  I bow to your opinion that they are questionable.

I am 3.5 miles away and only 50m higher than Dawyck up the Tweed and my 2022 readings for those dates were:

13 Dec 2022 min -14.1C max -6.0C

14 Dec 2022 min -10.3C max -7.2C

Seem plausible to me!
