The neighbouring Alpes-Maritimes have joined 27 other French Departements under a yellow alert for high temperatures.

The highest temperatures over the next few days are expected inland, but along the coast daytime high temperatures are set to exceed 30 degrees until next Thursday, August 24, according to Chaîne Météo.

In Monaco, there will be no escape from the heat at night, with temperatures falling only as far as 26 or 27.

From Friday, August 25, temperatures will fall slightly, with nighttime temperatures once again subsiding to a more livable 23 or 24.
