Produced by the health ministry the report looked at the period from July 1 to August 4.
The rise translated into more than 500 additional deaths, the health ministry said.
Mortality increased particularly in Reggio Calabria and Sicilian cities, where the effects of extreme heat were compounded by air pollution resulting from widespread wildfires.
Conversely, the mortality rate fell by 13 per cent among elderly people in cities in the north, which experienced unseasonal bad weather with heavy rainfall and low temperatures during the same period.
The report also highlighted how the strengthening of local health services, the implementation at local level of adaptation measures set out in the national plan and individual behaviour to reduce risks “are capable of protecting the population”, as shown by the limited impact of the heatwave on mortality in some cities.
