Data shows the impact climate change is having on the UK.
Data from the Met Office shows that more than half of the UK's oldest active weather stations had their hottest day ever.
During the July heat wave, new all-time highs were set at 56 stations.
The previous record was broken by one village.
This summer's extreme temperatures are a real indication of how our climate is changing, according to scientists at the Met Office.
According to the Met Office, it was the first time in history that temperatures passed 40C.
Active weather stations in the UK have had at least 50 years of observations.
The long- functioning stations that broke their previous records this summer did so by more than 2C.
There are large gaps between records in the chart.
The previous maximum temperature of 38.7C was set in the summer of 2019.
Coningsby does not have at least 50 years of data, so it is not included in the tally of stations that surpassed the record.
Mark McCarthy, head of the Met Office National Climate Information Centre, said that the northerly extent of extreme temperatures was notable.
West Yorkshire's Bramham smashed its previous high of 33.5C by more than 6 degrees.
Stations in parts of Yorkshire, the North East and the North West broke their all-time records.
The previous high set 40 years ago was more than 5C higher than the current one.
The new records were higher.
New national records were established in England, Scotland and Wales as a result of the summer heat.
These were set at stations with less than 50 years of data and are not included in this analysis, as the extreme heat this summer shattered multiple records related to specific stations across all four nations.
Only a small percentage of the UK's longest-standing weather stations have temperature records that were set before 2000.
In the past two decades, 80% of the total was set.
Leuchars station was the northernmost station to set a record. In 1990 it was beaten by 0.2C.
The previous national record of 35.2C was broken by Gogerddan, the first place in Wales to do so.
The longest record in the UK is held by the station in Northern Ireland.
The UK is experiencing more extreme heatwaves due to climate change.
The hottest day of the year has gone over 35C seven times. Five times in the 90 years prior, this happened.
In the last few years, the UK's record temperatures have been broken more often.
The record of 36.7C held for 81 years, but subsequent records stood for less than 20 years. The previous record was set three years ago.
Dr McCarthy said that the first recording of over 40C in the UK was a sign of how the climate is changing.
Transport disruption, wildfires and health implications affecting the population were some of the effects of the heat.
Europe as a whole saw temperature records shattered over the past few months.
It was the hottest summer on record in Europe due to a long-running dry spell and a series of extreme heatwaves.
In July, the highest temperature ever recorded in Portugal was 47C, while in France 64 different areas had record high temperatures.
Thousands of people were forced to leave their homes due to the fires.
The summer was the warmest on record.
