Overview

• Regional officials in Castilla y León urged residents in areas such as Valladolid and Palencia to wear masks, stay indoors when possible and avoid outdoor exercise due to elevated smoke.
• Meteorologist Francisco Cacho reported "extremely unfavorable" air quality in León, Zamora, Salamanca and Galicia driven by high PM2.5 and PM10 levels that pose greater risks for people with heart or lung disease, older adults and children.
• Northern Córdoba towns, including Pozoblanco, experienced heavy haze and burning odors, and the mayor clarified there are no local fires, attributing the smoke to active blazes in Extremadura.
• Dense haze reduced visibility in El Bierzo, complicating the use of aircraft in efforts to contain active fire fronts.
• The Junta de Castilla y León said conditions will fluctuate with wind and time of day in the coming days and advised residents to check local air‑quality updates before outdoor activity.
