UK Weather Forecast 2023: Will a Heatwave Hit the Country? Latest Updates
In the UK, a heatwave is defined by the Met Office as an extended period of hot weather relative to the expected conditions for that particular area and time of year, often accompanied by high humidity. The threshold for a heatwave is reached when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.
The heatwave temperature threshold varies across different UK counties. In Northern Ireland, Scotland, Wales, and the North and South West of England, the threshold is set at 25 degrees Celsius. In the South East of England, the threshold is slightly higher, at 27 degrees Celsius. Lastly, in some parts of the South East, such as London, the threshold is set at 28 degrees Celsius.
It's important to note that these thresholds are specific to the UK and may differ in other countries or regions. Monitoring heatwaves and issuing appropriate warnings is crucial to ensure public safety during periods of extreme heat.
