The peak of the third heatwave this year was on Thursday 9 July and Friday 10 July when temperatures reached 35C. Even though temperatures have fallen a little since then, some parts of the UK have still persistently reached 30C.
On Tuesday, the UK recorded 10 consecutive days of temperatures hitting 30C or more in some areas. Teddington, Richmond upon Thames, Kew Gardens and Heathrow, in London, are among the areas that exceeded 30C.
The very noticeable east to north-easterly wind has pushed the highest temperatures further west in recent days. But as the wind eases the heat will spread more widely and temperatures are forecast to rise higher this week.
The heatwave threshold is likely to be met in Scotland, Northern Ireland and northern England again.
