France recorded 5,700 more deaths than usual during its historic June heatwave

France recorded at least 5,700 more deaths than usual during a historic heatwave last month, the public health agency said Wednesday, sharply increasing its estimates of the feared toll from record-shattering temperatures.

Public Health France said regions hit by the heat from June 17 to July 2 recorded 21,674 deaths from all causes. But without a heatwave, those same regions would have been expected to have seen far fewer deaths, or 15,910, based on statistical modeling using data from previous years, it said.

The difference between expected and actual deaths — a total of 5,764 — are therefore considered to be “excess” deaths during the heatwave, the agency said.

It said the excess mortality, with 36% more deaths that would normally have been expected, was the highest from any heatwave since 2003. A historic heatwave that year caused an estimated 15,000 deaths in France.

France registered its hottest-ever days on June 24 and June 25 this year — with a national average of 30 C (86 F) — as well as record heat at night and peak temperatures that soared well above 40 C (104 F) in many places.

Just over half of the unexpected deaths occurred during and in the immediate wake of that hottest period, over three days from June 25 to June 27, the public health agency said.
