September in Spain is a month of change – summer slowly starts stepping aside but it’s still warm enough to enjoy the coast, festivals, and outdoor life. If you’re thinking of visiting Spain this time of year, knowing what to expect from the weather can really shape your trip in a good way. It’s not too hot, not too cold – a kind of sweet spot for travelers who like comfort but still want sun.

What Spain weather in September feels like

Spain weather in September is still pretty warm, especially in the first half of the month. Most of the country is holding on to those summer vibes. In the south, places like Seville or Córdoba can still hit 30°C (86°F) during the day. Meanwhile, up north around San Sebastián or Bilbao, temperatures tend to stay around 22°C (71°F), which feels cooler but still pleasant. Nights start to get a little fresher, so a light jacket or sweater won’t hurt.

You’ll also notice the air feels less heavy compared to July or August. There’s a touch of breeze in many parts and depending on the region, early signs of autumn slowly show up by late September.

Coastal weather vs inland Spain

Spain is kind of split when it comes to its climate. The Mediterranean coast – places like Barcelona, Valencia, Málaga – gets long sunny days, usually around 25-28°C (77-82°F) through most of September. You can still swim in the sea without freezing. The water’s been warming up all summer, so it’s at its best now.

Inland, like Madrid or Zaragoza, it’s hotter during the day but the temperature can drop fast once the sun goes down. It’s drier too. Less humidity means even 30°C doesn’t feel unbearable. You can walk around the cities comfortably, especially in the evening.

Is there much rain in Spain in September?

Rain is possible in September but it really depends where you are. Northern Spain gets more of it. Regions like Galicia or Asturias might have a few grey days, short showers, or even longer rain spells here and there. But nothing crazy or constant.

Central and southern Spain stay mostly dry. If it does rain, it’s usually quick and followed by sunshine again. Thunderstorms can happen, especially in areas near the mountains, but they tend to pass fast.

What to pack for Spain in September

This part is simple – think layers. Spain weather in September isn’t as extreme as midsummer, but it changes depending on the region and time of day.

Here’s a quick packing list:

• light t-shirts and tops
• shorts or skirts for daytime
• a sweater or light jacket for evenings
• maybe jeans or long pants for northern regions
• swimsuit if you’re heading to the coast
• good walking shoes or sandals
• umbrella or raincoat if you’re visiting the north

You’ll still want sunscreen too – the sun isn’t as harsh, but it’s definitely not gone.

Why September is a good time to visit Spain

Besides the pleasant Spain weather in September, there’s other good stuff too. Summer crowds start to leave, prices on flights and hotels drop a bit, and you don’t have to wait in line for everything. It’s a more relaxed vibe.

Also, festivals are still going strong. La Mercè in Barcelona happens late September and is full of parades, fireworks, concerts. Wine harvest festivals pop up in Rioja and other regions – perfect if you like local food and wine.

It’s a month that still feels alive but not overwhelming.
