As August transitions into September, Spain is experiencing a significant rise in temperatures. According to AEMET, an anticyclonic ridge is bringing warm air from North Africa, leading to extreme heat in several regions. 

In southern and central areas, temperatures are expected to reach extremes, with forecasts predicting up to 43 degrees Celsius in Córdoba or Badajoz, and 42 degrees in Jaén or near Seville. These heatwaves may be accompanied by episodes of calima, or dust in the atmosphere. In Talavera de la Reina, a new heatwave is expected to peak at 42 degrees by Friday.

Other regions are seeing varied conditions: Ferrolterra and parts of the north will see rising temperatures, while areas like La Rioja and Soria expect stable, sunny weather with moderate winds. In Mediterranean regions, such as Alicante and Valencia, temperatures remain high and summer-like, though some areas may see slight decreases or increased cloudiness mid-week.

Recent developments indicate the formation of a new heat dome expected to push temperatures exceeding 40°C across several cities. This weather system may eventually move east, potentially affecting parts of France and Italy. While extreme temperature contrasts are being noted in Albacete, record lows have been observed in Zamora.
