September in Spain begins with a sharp break from the long, dry summer. After weeks of record heat and devastating wildfires, the first days of the new month arrive with heavy rain, sudden storms, and a clear drop in temperatures across much of the country. For many, the unsettled skies mark a welcome reprieve.
The Iberian Peninsula is now under the influence of several low-pressure systems. Meteorologists point to two active weather fronts – one sweeping across the eastern Mediterranean, another pushing in from the northwest – combining to deliver turbulent conditions. After a season dominated by drought and flames, the arrival of wetter, fresher air offers both relief and disruption.

Storm risk from the Pyrenees to the Balearics
Forecasters warn that the most intense rainfall will fall in the northeast, particularly Catalonia and the Pyrenees, where hail is possible during the morning hours. The Balearic Islands face a similar threat, with torrential showers expected in the east of the archipelago. By late evening, the storm zone could extend to the coastal strip around Valencia.
Clouds roll in from the Atlantic
Galicia and the Cantabrian coast wake to overcast skies and steady rain. Scattered showers continue throughout the day along northern regions and the Balearics, often with thunder. Elsewhere, skies remain brighter but streaked with high clouds, a reminder of the seasonal shift.
Temperatures fall across Spain
The heat that dominated August is fading fast. In Burgos, the mercury will sink to just 12°C. Teruel holds at 21°C, while Santander, Palencia, and Cuenca hover around 24°C. Even in typically sweltering cities such as Seville, Valencia, and Alicante, maximums are expected to plateau at around 31°C. In the east and southeast, readings will stay comfortably below 34°C.
Winds add to the unsettled picture
Spain’s regional winds play a decisive role in the early September weather. The Canary Islands feel the steady trade winds, while the Ebro Valley braces for the cierzo – a cold, dry blast from the north. On the Balearics, the tramontana takes hold, shaping both skies and seas. Along the Cantabrian coast, gusts could reach damaging strength.
A taste of autumn ahead
While September in Spain often straddles the seasons, this year’s opening days lean firmly towards autumn. For holidaymakers, that means a mixed bag: relief from suffocating heat, but also sudden storms that may disrupt plans. For residents, it is a reminder that Spain’s climate is as varied as its landscapes – and that after fire comes rain.
