June has been confirmed as the most well liked on document for the UK.

This eclipsed the earlier document by 0.9°C, whereas the earlier prime three Junes had been separated by simply 0.1°C.
Fingerprint of local weather change
A fast examine by Met Workplace scientists discovered the prospect of observing a June beating the earlier document of 14.9°C, like now we have this yr, has at the very least doubled because the interval round 1940. The earlier document of 14.9°C was recorded in 1940 and 1976.
Paul Davies, Met Workplace Local weather Extremes Principal Fellow and Chief Meteorologist, explains: “We discovered that the prospect of observing a June beating the earlier joint 1940/1976 document of 14.9°C has at the very least doubled because the Nineteen Forties. Alongside pure variability, the background warming of the Earth’s environment because of human induced local weather change has pushed up the opportunity of reaching document excessive temperatures.
“Utilizing our UKCP18 local weather projections, we are able to additionally see that there’s a distinction within the frequency of those type of extremes relying on the emissions state of affairs we observe sooner or later. By the 2050s the prospect of surpassing the earlier document of 14.9°C might be as excessive as round 50%, or each different yr. Past the 2050s the chances are strongly ruled by our emissions of greenhouse gasses, with the prospect rising additional in a excessive emissions state of affairs however levelling off beneath mitigation.”
The fast examine used the UK’s local weather projections, UKCP18, evaluating the prospect of surpassing 14.9°C through the interval 1925-1955 to that for 1991-2020.
Lengthy-lasting warmth
The UK, in addition to England, Scotland, Wales and Northern Eire all recorded their respective warmest June in a sequence which dates again to 1884, some by a major margin.
Spurred on by mid-month warmth, the UK’s imply temperature for June 2023 was 15.8°C, some 2.5°C increased than common.
The Met Workplace’s Mark McCarthy, who works within the group accountable for climate and local weather data, stated: “It’s formally the most well liked June on document for the UK, for imply temperature in addition to common most and minimal temperature.
“June began with a great deal of excessive strain and temperatures initially round common for a lot of, however as soon as that subsided, heat, humid air started to affect temperatures, with 32.2°C the best temperatures reached.
“What’s putting is the persistent heat for a lot of the month, with temperatures extensively into the mid 20s Celsius for a lot of and even into the low 30s at instances.”
Eight of the twelve calendar months now have a mean temperature document set since 2006 in a sequence which dates again to 1884.
An enormous 72 ceremonial counties within the Met Workplace system recorded their hottest June on document, with many recording imply temperature greater than 2.5°C greater than common. Counties that recorded their warmest June on document stretched throughout a big space of the UK, together with Orkney, Warwickshire, Surrey, Somerset and Cornwall.
Did the marine heatwave impression temperatures?
The North Atlantic, together with waters across the UK, has been experiencing record-breaking temperatures of its personal in June, which has performed an underlying position within the land-based temperature figures for the UK.
Met Workplace Scientific Supervisor Segolene Berthou stated: “These settled circumstances additionally contributed to a quick warming of the ocean floor across the British Isles: a extreme marine heatwave was declared mid-June (NOAA – Class 4). Provisional findings from the Met Workplace counsel this marine heatwave in flip amplified land temperatures even additional to the document ranges seen through the month.”
Sunniest June since 1957 for UK
With a interval of excessive strain serving to temperatures to climb, it additionally created lengthy durations of sunshine for a lot of, with the UK recording its sunniest June since 1957 and its fourth sunniest on document.
Scotland has its third sunniest June on document with 231.4 hours of sunshine. England had its fourth sunniest with 259.8 hours. Northern Eire had its eighth sunniest on document with 228.7 hours of sunshine, whereas Wales had its ninth sunniest with 242.8 hours.
A dry month, regardless of an unsettled finish
Rainfall was in brief provide for a lot of June, although totals did climb within the second half of the month. The UK had simply 68% of its common rainfall for the month, with 52.2mm of rainfall.
