Spain braces for a dramatic weather reversal. After days above 40°C, forecasts point to rain, wind, and cooler air, especially in the north. Meteorologist Jorge Rey signals a turning point for the season.
Spain is about to see a sharp change in weather after a stretch of intense September heat. Meteorologist Jorge Rey points to next week as the moment when temperatures will drop, especially in the north, with more clouds, rain, and wind moving in. Cities like Seville are still expected to reach 43°C before the shift arrives.
For now, the heatwave continues. Much of the country remains under weather alerts as temperatures stay dangerously high. Rey notes that while the change will be clear, it does not mean cold weather is coming. Instead, people can expect a break from the extreme heat, with milder temperatures and higher humidity as showers and clouds appear. Spain's national meteorological agency, AEMET, has confirmed the early September heatwave, with many inland areas well above normal and tropical nights above 20°C likely to last through the weekend, according to Reuters.
In early September, AEMET activated weather warnings in several regions, including Andalusia, for temperatures up to 40°C, thunderstorms, hail, and strong winds.
The north will feel the biggest impact, with rain and wind expected to be strongest there. Rey says the most noticeable change will likely come on Wednesday, September 9, when the new pattern sets in. This is not expected to be a one-day event. As mid-September approaches, forecasts suggest Atlantic storms could pass near Spain, bringing more unstable weather and several drops in temperature. Official outlooks show that most of Spain will stay warmer than usual for the first half of September, but the north faces a higher risk of rain and the east and interior could see local storms. AEMET stresses that this does not mean a lasting cold spell, but rather a back-and-forth between heat and unsettled weather.
Even with these changes, summer is not over. Rey warns that September will still bring warm days, but these will be mixed with cooler spells and unsettled skies. This pattern of alternating heat and relief is likely to continue, with a chance of more cooling toward the end of the month as storm systems get closer to the Iberian Peninsula. Private weather reports for September 1–2 confirm that the most extreme heat was in southern and central Spain, with Córdoba, Seville, and Badajoz reaching 41–44°C, while the Mediterranean coast stayed milder.
Looking ahead, the changing weather could signal a broader shift in the season. Rey notes that trends in late September may set the stage for October, with more unstable conditions and a slow move away from the persistent heat that started the month. This matches recent warnings about severe storms in the north, as reported earlier.
According to Reuters, the extreme heat in Spain last month was linked to 2,149 deaths, underscoring the serious public health impact of prolonged high temperatures. The humanitarian significance of new heat episodes and official health warnings is heightened by this recent statistic.
September weather in Spain is famously unpredictable, often swinging between late-summer heat and the first signs of autumn. The current forecast makes it clear that residents, especially in the north, should be ready for quick changes. The coming drop in temperatures will bring relief from the heat, but also marks the start of a more unsettled period. Anyone planning travel, outdoor work, or events should keep an eye on the forecast, as the risk of sudden storms and cooler weather is rising. Summer is not finished, but the steady pattern of the season is breaking, and people will need to adapt in the weeks ahead.
