Overview

• Aemet’s provisional analysis sets the August event as the most intense on record with a 4.6 °C anomaly over a 16‑day span, including the warmest 10 consecutive days on record from 8 to 17 August and the warmest 1–20 August since at least 1961.
• With national temperatures lower since mid‑month, Aemet issued yellow alerts on Tuesday in Extremadura for highs of 36–37 °C in areas such as Villuercas y Montánchez and the north of Cáceres.
• A tongue of Saharan dust is clouding skies across Andalusia as highs reach about 37 °C in Granada, Jaén and Córdoba under yellow alerts, with the calima expected to dissipate from Wednesday afternoon and a broader cooldown by Thursday.
• MeteoGalicia forecasts a return to typical summer instability and rain in the northwest this week as the Azores anticyclone retreats, following an unusually warm and dry August in the region.
• In Catalonia, Tuesday is expected to be the week’s warmest day before a marked temperature drop on Wednesday with storms and rain under Meteocat advisories, while Aemet indicates August 2025 will likely rank among the four warmest Augusts and this summer among the two hottest on record.
