After the last heatwave featured a number of nights when temperatures didn’t fall below 20C (68F) – also known as a tropical night – this spell of hot weather will be more forgiving.
Nighttime temperatures are not expected to be as high as those experienced in June, though some larger urban areas are likely to remain in the high teens overnight. This is especially likely later in the week.
It is not out of the question that a tropical night may be recorded in a few places.
Although this heatwave will allow for some overnight relief, the length of the hot spell will set it apart from those seen in May and June.
The current forecasts suggests a temperature could exceed 30C somewhere in the UK for up to 10 consecutive days.
During the June heatwave the temperature exceeded 30C somewhere in the UK on seven consecutive days. In the May heatwave, it was six days.
