Austria In June heat records were broken, on 30 June the temperature reached in
Innsbruck. This was a heat record for June in Austria, and also the highest temperature measured during the heatwaves.
Belgium Belgium recorded three consecutive days exceeding ; 25 June was the hottest day during this period, with many places exceeding and other places nearly reaching . During the period of hot weather, environmental officials warned of poor air quality levels, which would especially affect the young, elderly and people with respiratory illnesses. It also affects small countries that rely on tourism as their main source of income. On 24 July, the highest ever recorded temperature in
Belgium was measured, reaching in the town of
Angleur, exceeding the previous record of , reached in 1947. On the same day, passengers were evacuated from a
Eurostar train that had broken down between
Halle and
Tubize, as many began to fall ill due to the extreme temperatures. On 25 July, the national record was broken again, reaching in
Begijnendijk (
Flemish Brabant). One death was reported. The official KMI weather station in Uccle reported a maximum temperature of , while many other weather stations, some even close to the North Sea, reported temperatures in excess of .
Czech Republic The temperature record for June was recorded in
Doksany and was . High temperatures also complicated rail transport in the
Czech Republic.
Finland On 28 July,
Helsinki recorded a temperature of , breaking the city's previous record. On the same day, was recorded in
Porvoo.
France France was one of the most affected countries from the heatwave, with much of the country exceeding on 26 June. Météo France issued an Orange Alert for much of the country due to exceptionally hot temperatures, excluding coastal regions, e.g.
Brittany and the northern part of
Hauts-de-France. Four departments of France were put on Red Alert:
Bouches-du-Rhône,
Gard,
Hérault and
Vaucluse. Owing to building codes with old structures common across the country, numerous buildings in France lack air conditioning. Museums with air conditioning allowed free entry for all people. These exceeded the previous record of , recorded in
Conqueyrac and
Saint-Christol-lès-Alès. Five people died nationwide: four from drowning and one from heat stroke. Police noted an increase in instances of illegal
fire hydrant openings. A six-year-old child was hospitalised in critical condition after being hit by a stream of water from an illegally opened hydrant. More than 50 French cities exceeded their previous high temperature records in this heat wave. On 24 July, a temperature of was registered by Météo-France in
Bordeaux, breaking the city's previous record of in 2003. Similarly, on 25 July, a temperature of was recorded in
Paris, also breaking the city's previous record of in July 1947. On the night of 24–25 July, France saw its hottest night since records began, as the whole country averaged an overnight low of , exceeding the record from the 2003 heat wave. Bordeaux saw an overnight low of , beating the previous record of 25 °C (77 °F, 2006);
Lille saw , exceeding the
July 2007 record of . Lille also saw a high of the following day, above the record of that had been set
the previous year. On 25 July, the chief architect of the
Notre-Dame de Paris cathedral told media that he feared that the heat wave could cause the cathedral's vaulted ceilings, damaged in
an April 2019 fire, to collapse. While he indicated the stone walls were still stable for the time being, he explained that the walls were still saturated with water sprayed by firefighters during the blaze, and rapid drying from the extreme temperatures could adversely affect the stability of the structure. Two
nuclear reactors in southwest France were shut down and the output of six reactors were curtailed to avoid breaching environmental limits on the temperature of the rivers they use for cooling water. This reduced French nuclear power generation by around 5.2 gigawatts at a time of increased electricity demand due to the use of cooling devices.
Germany Most of
Germany recorded temperatures exceeding on 26 June as well as large parts of the country exceeding . Temperatures as high as were recorded in Berlin-Tempelhof, and Brandenburg had temperatures reaching , exceeding the previous June record of recorded in Frankfurt.

Germany, following its previous record of measured a day earlier. Twenty-five
weather stations in the country reported temperatures of or higher on 25 July. At the end of the heat wave, on the evening of 26 July, a maximum purple alert for storms was issued for three
districts (
Landkreise) of the
Land Baden-Württemberg, namely
Freudenstadt,
Böblingen and
Calw.
Greenland After the heat wave ended in mainland Europe, the mass of warm air traveled north to Greenland, causing a heat wave that led to a melting of some of ice in July. The melting was forecast to peak on 1 August. For comparison, the entire melt season in 2012 caused of ice loss. A record 56.5 percent of
Greenland Ice Sheet was showing signs of melting on 31 July. US
National Snow and Ice Data Center estimated ice loss during the first week of August at per day with a total loss of for the melt season to date. A wild fire which has been burning near
Sisimiut since early July necessitated dispatching firefighters from
Denmark, as the fire was endangering inhabited areas and had the potential to continue burning through the winter. Forest fires are exceedingly rare in Greenland.
Italy By 28 June, Italian authorities placed 16 cities under high alert for dangerous temperatures. Civil security services distributed water to tourists visiting
Rome.
Luxembourg On 25 July, a red alert for extreme heat was put in place for the entire country by Meteolux. The same day, a temperature of was measured in
Steinsel, the highest ever recorded in the country, beating the record of set in
Remich in
2003. The high heat and dry conditions caused several fires during the heat wave. On 24 July, a fire broke out near Schumannseck, and
hay bales caught fire in a field. On 25 July, a bush fire occurred in
Hamm, and a fire truck exploded when it became engulfed in flames whilst attending the scene.
Netherlands On 25 June, much of the inland areas of the
Netherlands exceeded . The

RIVM also put National Heat Plans into force in areas issued under code yellow.
De Bilt, where the headquarters of the KNMI is located, recorded a temperature of , and parts of
Uden and
Gelderland recorded temperatures as high as . In July in the Netherlands, an orange alert was put in place for the entire country due to the extreme heat. The following day, was measured in
Gilze-Rijen (also North Brabant). The
West Frisian Islands was the only region for which no weather alert had been issued but there was a heatwave for the first time ever on
Vlieland and
Terschelling since measurements started in 1996. On 27 July, the
KNMI ended the orange alert for
South Holland,
Zeeland,
North Brabant and
Limburg. The same day at 22:32
CEST they ended the orange alert for the whole country. On 25 July,
NS cancelled services on the
Schiphol–Antwerp high-speed railway between
Amsterdam—
Schiphol— Rotterdam, and the connection between Amsterdam—
Eindhoven and Eindhoven—
Heerlen. As trains were exposed to high temperatures, more maintenance was required and some were taken out of service. Units without air conditioning or openable windows were also taken out of service. This continued into the following day, except with four other routes made unavailable; Amsterdam—
Alkmaar, Amsterdam—
The Hague,
Duivendrecht—
Lelystad and Schiphol—
Nijmegen. Many farm animals died as a result of the high temperatures, mainly due to ventilation systems failing. Due to a power failure in a chicken barn in
Neer, 4,000 chickens died. Hundreds of chickens also died whilst being transported to
Poland on 24 July because of rising temperatures. On the same day, hundreds of pigs died in
Middelharnis because of power failure in ventilation systems, and 2,100 pigs died in
Maarheeze as barns reached temperatures of . Nearly 400 extra people were reported to have died during the heatwave compared to a regular summer week. However, the Norwegian Meteorological Institute later did not approve the recording due to too much gravel and too high vegetation near the station. The highest recording approved was at the
Mosjøen Airport on 27 July, the warmest temperature ever recorded in Northern Norway and a tie with the all-time national high for July. The same day, a temperature of was recorded further north in
Saltdal Municipality. This is highest temperature ever recorded inside the
Arctic Circle in Norway. On 27 July,
Trondheim Airport recorded a new all-time high with and saw five consecutive days with high above . At Sømna-Kvaløyfjellet, a weather station on a coastal hill ASL in
Nordland in Northern Norway (), the overnight low on 28 July did not go below , beating the previous national record for the warmest night of recorded 6 degrees of latitude further south in
Halden Municipality, south of Oslo, in July 1933. The
Norwegian Meteorological Institute said that it had recorded "tropical nights" in 20 locations in the south of the country, where temperatures stayed above throughout the night.
Poland Poland recorded high temperatures early in June, with much of the country exceeding on 12 June. Like much of Western and Central Europe, most of Poland recorded temperatures as high as on 26 June. Poland has also exceeded its previous June record, recording in Radzyń.

Valladolid and a 17-year-old boy in
Córdoba. A
wildfire broke out in
La Torre de l'Espanyol within the
Province of Tarragona in
Catalonia on 26 June. By 28 June more than 600 firefighters and six aircraft were deployed to combat the blaze. One of
Ascó's Nuclear Power Plant evacuation power lines was near the site the fire started, so it was subsequently switched off in an attempt to aid with the fire extinguishing tasks. The plant continued to operate normally throughout the days.
Sweden Sweden was only affected in the southern portion of the country. On 30 June
Oskarshamn measured the highest June temperature since 1970. On 26 July, a temperature of was recorded in
Markusvinsa, the highest temperature recorded in the north of
Sweden since 1945. The
Swedish Meteorological and Hydrological Institute issued a Class 1 heat warning for parts of the country, as well as a warning for potential water shortages in August in 15 counties. To prevent forest fires due to the heat and dry weather, fire bans were put in place in several locations in Sweden. A meteorologist at the institute stated that although above average, temperatures in the south of the country were not as extreme. Areas with high altitudes also exceeded , with temperatures reaching as high as in
Col Des Mosses and
Adelboden. MeteoSwiss issued a Level 3 hazard due to high temperatures for much of the country, with large parts of
Valais and
Ticino under a Level 4 hazard, meaning high danger due to the exceptional heat. The highest temperature measured during the heatwaves was on 25 July in
Basel.
United Kingdom On 29 June large parts of England, including the South and the Midlands, faced temperatures exceeding with the highest temperature of recorded at
Heathrow Airport and
RAF Northolt. The heatwave was rather short lived in the United Kingdom, with temperatures dropping to near normal the next day. One child drowned in the
River Irwell in
Greater Manchester after diving in to cool off during high temperatures. On the same night, widespread thunderstorms affected the country, with
BBC Weather reporting around 48,000 lightning strikes overnight. On 25 July, the Met Office announced that the United Kingdom had its hottest July day on record, with a temperature of recorded in Rainham Kent.

Edinburgh and in
Sheffield.
Impact on British transport and flights On 25 July,
Network Rail began to impose speed restrictions across its network to reduce buckling rails, as track temperatures surpassed . Measures included painting railway tracks white to reduce the temperature of the steel, and cancelling services.
East Midlands Trains,
Southeastern and
Greater Anglia advised passengers against all but essential travel. Many heat-related incidents on the country's rail network caused widespread disruptions, especially affecting intercity services from
London. Damage to overhead line equipment occurred in
Peterborough,
Handsworth and
Camden, as well as a trackside grass fire caused by cables snapping near
West Hampstead. Trains arriving and departing from
Birmingham New Street and around the
West Midlands were also disrupted. Passengers were advised not to start new journeys as the overheating of overhead cables rendered many services unable to run. On 26 July, all but essential travel had been advised against, after the extreme heat and storms caused severe disruption to the rail network and airports.
Thameslink ran reduced services, with half of its lines unavailable. East Midlands Trains services between
Sheffield,
Nottingham,
Derby and
London St Pancras were disrupted due to overhead wire damage from the heat of the previous day, and an emergency timetable was put in place. All Eurostar services to and from Paris were suspended for an "undetermined amount of time" due to an exploded cable, as well as delays lasting up to an hour on
Brussels services. Several flights were cancelled and delayed from
Heathrow,
Gatwick and
London City airports due to "extreme weather conditions across Europe". A spokesperson from Heathrow said that flights had been affected by overnight storms as a result of the heat. == Highest temperature per country ==
