Record mensuel de chaleur d'août aussi à l'Observatoire Fabre de #Barcelone hier 16-8-2025, avec une température maximale de 38.9°C, battant les 38.8°C du 23-8-2023 (mesures depuis 1913).
Le record absolu annuel sur cette station historique de référence date de l'été dernier (40.0°C, 30-7-2024).

A falta de confirmació oficial l'Observatori Fabra de Barcelona ha arribat avui als 39 °C, valor més elevat en un agost des del 1913. La mitjana de la temperatura màxima anual ha passat de 33,1 °C (1914-1943) als actuals 35,3 °C (1996-2025), i això té un nom: canvi climàtic.

The heatwave in Sodankylä has now lasted for 26 days.

This is probably not only the longest heatwave in Lapland, but also the longest heatwave ever observed in Finland.

Note that here a heatwave is defined with 3 consecutive days above 90th percentile, which is scientifically robust definition.

Time series graph showing the duration of longest heatwave event in Sodankylä Tähtelä. The values range generally between 0 and 14, but in 2025 the heatwave has now lasted for 26 days.

Record absolu de température observée au niveau 500 hPa au radiosondage de ce matin de Payerne : -4,3°C à près de 6000 m d'altitude !
D'autant plus remarquable que toutes les autres valeurs élevées ont été observées en fin d'été, quand les masses d'air sont encore plus chaudes à ce niveau.
