What is a heatwave?

For a heatwave to be declared a threshold determined by the Met Office must be met.

The UK heatwave threshold is described on the Met Office website as: “when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.”

The initial heatwave thresholds were calculated based on the 1981-2010 climatology of daily maximum temperature at the midpoint of the meteorological summer (15 July). In 2022, the Met Office updated the threshold.

The threshold for a heatwave temperature differs by county, with some areas in the southeast having a threshold of 28°C, while areas to the north and west have a threshold of 25°C.
