What is the definition of a heatwave?
Many areas will reach the official heatwave criteria of three consecutive days of high heat, which varies from 25 to 28C depending on the region of the UK.
In May, the UK faced an unprecedented spring heatwave with temperature records broken across the country, including in Sheffield.
According to the Met Office, the spring weather event was "one of the UK's most extreme high temperature events in our observational records".
