Temperatures across the globe of course differ widely, depending on what country and continent you're in. The definition of a heatwave can also vary from country to country.
There is no official definition of a heatwave in the UK but the one those associated with the Met Office tend to use is that issued by the World Meteorological Organisation....
Over the past 5 days we have indeed seen temperatures 5 degrees above the average (15-16°C) for 5 days in a row.
Our hottest day was Monday the 19th May, where afternoon temperatures reached 25°C at our Met Office data sites near Chester and Crosby.
Conditions will gradually cool down over the next few days with temperatures back down to the May average by the end of the week.
