The Spanish weather service Agencia Estatal de Meteorología (Aemet) is forecasting a further marked rise in temperatures across many parts of the country over the weekend and at the start of next week. Daytime highs are expected to reach 32 to 35 degrees across widespread areas, and locally higher. The forecast identifies the north-west and north as particularly affected, with temperatures rising in Galicia, along the Cantabrian coast and in the upper Ebro, as well as across much of Andalusia and Extremadura. In low-lying areas on the southern Atlantic side, such as the Guadalquivir Basin, temperatures may exceed 35 degrees. Above-average temperatures are also expected in the south of the Canary Islands.
Television meteorologist Roberto Brasero (Antena 3) had previously said in a video report that the brief cool spell, with autumnal winds and thunderstorms, was “just an illusion of autumn” and that “the heat has not had its last word yet”. His assessment is consistent with Aemet’s latest daily forecasts, which show temperatures rising further over the coming days.
Aemet also places this development in its seasonal outlook for September to November 2026: the probability of above-average temperatures is elevated across large parts of Spain. Experts note that September highs of around 32 to 35 degrees can be several degrees above the long-term average. This increases the strain on vulnerable groups, affects electricity demand and the power grid, and raises the risk of wildfires in some areas.
Specific warning levels are determined locally. Aemet and the regional authorities point to their regularly updated maps and notices, which may be adjusted at short notice as air masses develop. The figures given are forecasts, not certainties; any intensification or easing will depend on the wider weather pattern. Media reports, including Antena 3’s coverage, reflect this situation and are supported by official forecasts.
Spain has once again experienced marked inflows of warm air from southern latitudes since the end of summer. For the coming days, models point to stable high-pressure conditions, with plenty of sunshine and correspondingly strong warming in the afternoons. Cooler air masses from the west could make an impact later in the week; this possibility remains uncertain at present and will be subject to the next forecast update.
