What is a heatwave?

The word ‘heatwave’ is thrown around regularly when it comes to weather forecasts across the globe - but what is a heatwave?

According to the Met Office, a heatwave is an extended period of hot weather relative to the expected conditions of the area at that time of the year.

In the United Kingdom, this is the criteria the weather must meet to be considered a heatwave:

  • When a location records three consecutive days with a maximum temperature that exceeds the threshold (this varies depending on the county)

For example, Liverpool and the surrounding Merseyside area has a threshold of 25℃.
