A provisional temperature of 40.2 °C (104.3 °F) was recorded at Heathrow, UK at 12:50 LT on July 19, 2022, which, if confirmed, will beat the previous record of 38.7 °C (101.6 °F) set in 2019 by 1.5 °C (2.7 °F).
With temperatures continuing to climb through the afternoon we will have to wait to see what the new record will actually be.
New temperature records could also be set for Wales and Scotland, UK Met Office said.1
The first-ever Red Extreme Heat warning is still in place across parts of England and a more extensive Amber Extreme heat warning, covering much of England, Wales and southern Scotland.
With the extreme heat today comes the risk of thunderstorms, particularly in parts of the southwest today and, later, the northeast of England.
A Yellow Thunderstorm Warning has been issued for parts of the Southeast tomorrow.
“We are continuing to see exceptional temperatures in the UK today and it is important people plan for the heat and consider changing their routines. This level of heat can have adverse health effects,” said Neil Armstrong, Met Office Chief Meteorologist.
Temperatures are expected to start to return closer to normal for the time of year as we go through the rest of the week with cooler air pushing across the country from the west.
“We have seen temperature records tumbling. A new UK national climate temperature record should be a rare occurrence, and we would normally expect a new record to only exceed the previous one by a fraction of a degree,” the head of the Met Office National Climate Information Centre, Mark McCarthy, said.2
“However, yesterday we saw 39 stations across a large swathe of England exceed the previous highest daily temperature extreme, with the highest exceeding the previous record – set in Cambridge in July 2019 – by a remarkable 1.6 °C (2.8 °F).”
“A factor of the recent extreme hot spell were the overnight temperatures which also broke previous records by a large margin with Kenley Airfield, Greater London recording a minimum of 25.8 °C (78.4 °F) beating the previous record by 1.9 °C (3.4 °F).
“At country and regional level the previous two days has also seen Wales and Scotland produce new national maximum temperature records.”
