Ministers in France are meeting to assess the country’s preparedness for heatwaves, while tennis number one Jannik Sinner bowed out of the French Open after suffering from the heat. Meanwhile,Italian authorities issued a red heatwave alert for the capital, Rome, where it topped out at 32C on Thursday.
The heatwave is forecast to continue into the weekend, with Germany, Spain and Switzerland having also faced unusually hot conditions.
Parts of Portugal will peak above 35C on Fridaybefore the heat begins to recede, according to the nation’s meteorological office.
French Prime Minister Sébastien Lecornu chaired a ministerial meeting on Thursday afternoon to develop a readiness plan for extreme heat events, including combating forest fires and ensuring adequate water supplies over the summer.
Baccalaureate exams – the French equivalent of A-levels – will continue during the heatwaves, despite some schools having to shut their doors due to inhospitable temperatures inside.
A primary school in Souston, in the Landes region, will remain shut on Friday after it reached 53C inside earlier in the week, a local official told French media.
Education Minister Édouard Geffray told BFMTV that exam centres would be able to choose rooms with the most shade, adding that exams would go ahead “simply because the students are prepared and… there is also a schedule according to which they expect their results”.
The decision has attracted criticism from education unions and teachers, with one telling French radio of teachers “forced to bring in their own fans”.

Temperatures will climb to 35C in Madrid over the weekend. Though the current spell does not officially qualify as a heatwave in Spain, the nation’s meteorological office has said the heat is that usually seen in July and August.
The immediate cause of the heatwave is a “heat dome” – an area of high pressure that becomes “stuck”, trapping warm air underneath it.
While it is difficult to link individual extreme weather events to climate change, scientists say climate change makes heatwaves more frequent and more intense.
Over the last 30 years, Europe has been warming by 0.56C per decade, according to the Copernicus climate service – enough to make heat extremes significantly more severe.
The UN warned on Thursday that global average temperatures were likely to continue at or near record levels this year and for the next four years.
