Madrid heads into a weekend of unrelenting heat, with the mercury hitting 33°C and little sign of a break. High clouds do little to block the sun, and nearby towns are even hotter. The forecast points to tough days ahead for everyone in the city.
Thermometers in Madrid shot up again this weekend. The city faced 33 degrees Celsius under a thin layer of high clouds. AEMET, Spain’s state weather agency, warned that relief would be hard to find. Daytime highs barely moved from Friday’s mark. Nights stayed warm, with lows only dropping to 18 degrees. That’s not much comfort for anyone hoping to cool off after sunset.
Saturday brought no surprises. High clouds hung overhead, but the sun still burned through. Outdoor plans turned into a test of stamina. The minimum temperature hovered near 18 degrees, but it felt closer to 19. Even early mornings stayed sticky. AEMET said these numbers are 5 to 10 degrees above what’s normal for late September. That’s a big jump for this time of year.
AEMET issued yellow-level heat warnings for several Spanish regions, including Castilla-La Mancha, Extremadura, Aragón, Andalucía, and the Canary Islands, due to persistently high temperatures.
Sunday’s outlook barely changed. High clouds stuck around. The top temperature eased a bit, landing at 30 degrees. But the low crept up, with a “feels like” temperature near 20. Another tough night for sleep. Independent summaries of AEMET forecasts confirmed almost no chance of rain. The heat was set to drag on through the weekend.
Monday offered a hint of change. Not much, though. There was a small chance of rain. The day would start with more high clouds, then clear up a bit by midday. Highs would drop to 28 degrees, with lows again at 18. Light breezes from the south were expected, but they wouldn’t do much to cool things down. AEMET updates its warnings and forecasts up to 72 hours ahead. Residents should keep an eye on the latest bulletins for any shifts.
Outside Madrid, the heat only got worse. In Las Rozas de Madrid, the day would start with a few clouds. By midday, high clouds would take over. Temperatures would swing from a cool 15 degrees at dawn to a blazing 34 in the afternoon. Brunete faced the same story. High clouds, with temperatures ranging from 17 to 34 degrees.
By the end of the week, much of central and southern Spain was experiencing a very warm air mass, with interior regions reaching 32–38°C and some southwestern areas, such as the Guadalquivir valley, seeing peaks of 39–40°C. This widespread heat explains why Madrid's conditions are considered part of a broader heatwave affecting the country.
Other towns in the region—Guadalajara, Segovia, Ávila, Talavera de la Reina, Ciudad Real, Salamanca, León, Castelldefels, Badajoz, Elche, Granada, Calahorra, Logroño, and Santa Lucía de Tirajana—were also bracing for similar heat. Local differences would matter, but the trend was clear. Data from AEMET and other sources was still provisional and could change as the situation developed.
Spain’s swings between heat and cold have been a talking point for years. As reported earlier in the context of the winter time switch, the country’s approach to time changes and weather adaptation keeps coming up. This heatwave shows just how quickly Spanish weather can flip between extremes.
Madrid’s latest forecast is a blunt reminder. The city is exposed when summer heat hits hard, especially with high clouds that barely block the sun. Only small changes are expected in the coming days. People in Madrid need to get ready for more tough weather. The next stretch looks rough. Stay alert and take care as the city sweats through another fierce spell of summer heat.
