Spain is facing a sharp drop in temperatures towards the end of the week. According to Agencia Estatal de Meteorología (Aemet) a new front is moving in from the west, bringing renewed rainfall and a noticeable cooldown overnight from Thursday to Friday (27/28 August 2026). Between 7 and 8 a.m. on Friday, temperatures could fall below 10°C in at least 13 provincial capitals will record temperatures below 10°C.
According to the current forecast, the north-west of the Iberian Peninsula will be hardest hit. Early-morning temperatures of around 8 to 9°C are expected in the eleven provincial capitals of Castilla y León ; forecasts for Lugo and Oviedo are around 9°C. The cooldown follows several Atlantic fronts that have already brought showers and thunderstorms to large parts of the peninsula since the start of the week. Aemet attributes the current weather pattern to a trough from the Atlantic, followed by a “entrada fría”, bringing cooler air at ground level and generally lower temperatures.
Aemet is forecasting further widespread rainfall on Wednesday and Thursday, particularly in Galicia and other parts of the north-west. The agency expects the cooldown to peak on Thursday evening and overnight into Friday, with daytime highs remaining subdued in some areas on Friday. As is usual during summer transition weather, individual city forecasts are uncertain; however, several model runs consistently point to below-average early-morning temperatures in the north-west and northern inland areas.
The weather will have different regional effects: heavier showers are possible in Galicia and on the northern slopes of the Cantabrian Mountains, while the notable morning cooldown will be most pronounced inland in Castilla y León. Unsettled weather may return temporarily along some north-eastern coastal stretches and in the Balearic Islands, although the likelihood of such low early-morning temperatures is lower there.
Specific minimum temperatures are based on Aemet forecasts and updates available up to Tuesday, 25 August 2026. Further adjustments may follow in the next model runs. What is clear is that expected early-morning temperatures in many northern and north-western regions are well below what is usual at the end of August. Locally, this will make an extra layer of clothing useful in the early morning, while rain may temporarily ease drought in parts of the north.
