Madrid will close out September under clouds and with a real drop in temperatures. The State Meteorological Agency expects scattered showers, especially in the Sierra, and highs that stay below 30 degrees. Autumn is here.
Madrid’s run of summer heat has ended. This week, the city won’t see temperatures above 30 degrees. Instead, clouds and scattered rain are moving in. The State Meteorological Agency (Aemet) says Wednesday will bring overcast skies and warmer nights. For many, it’s the first real taste of autumn. Independent weather sources like Infobae and Clarin agree: Madrid’s highs will sit between 25°C and 27°C, with lows from 15.9°C to 18°C. The cooling trend is clear.
The Sierra de Madrid will get the most rain. Showers are most likely in the morning. Aemet puts the chance of rain at 45% early on, rising to 80% by Thursday afternoon. By Friday, it hits 100%. People living on the higher northern slopes may see mist and fog by evening. Tutiempo reported early clouds and light rain around 06:00, but skies cleared up by midday.
Spain entered a phase of abrupt weather change at the end of September, with AEMET issuing orange-level alerts for heavy rain and storms in five autonomous communities, especially in Catalonia.
Madrid itself has a simple forecast. Lows will reach 18 degrees. Highs won’t go past 25. Across the region, maximums will stay between 25 and 28 degrees. The 30-degree mark is out of reach. Winds will be light and change from southwest to west during the day. Majorca Daily Bulletin links these changes to new atmospheric fronts and a trough of low pressure over the Iberian Peninsula. This isn’t just a local blip.
The unsettled weather will stick around. After Wednesday, lows will drop and settle near 15 degrees. Highs will fall to 26 or even 24 degrees by the weekend. The rain isn’t leaving. Aemet expects a 100% chance of rain on both Friday and Saturday, and 95% on Sunday. The agency forecasts 16/24 degrees on Friday, 14/22 on Saturday, and 14/23 on Sunday. Madrid will start October wet. Independent forecasts back this up, pointing to steady rain and falling temperatures as the week goes on.
Spain as a whole is in for a rough weather week. Earlier reports warned of storms and sudden temperature drops in several regions. Madrid, though, isn’t facing wild extremes. The city is just moving out of summer, step by step. Europa Press and Infobae say the worst weather has hit the east and northeast, especially Catalonia. There, rainfall reached up to 40 liters per square meter in an hour.
The broader context for this weather shift is the movement of atmospheric fronts and a trough of low pressure over the Iberian Peninsula, which has brought widespread rain and cooler temperatures across Spain. While Madrid experiences a mild autumnal transition, other regions—especially in the northeast—have faced more intense storms and official weather warnings.
Madrid’s forecast stands out for its calm. No wild swings. Just steady rain and mild temperatures. Autumn has arrived. For locals, it means a break from the heat and umbrellas back in hand. The city’s weather can change without drama. The next few days will show how fast Madrid settles into a slower, wetter pace. Summer is done. Autumn is here to stay.
