Spain in September: Warm Days, Cool Nights

When I think back to my trip to Spain in September, I remember the delightful transition from summer to fall. The weather was still warm, and the country felt less crowded. This is the perfect time for sightseeing, road-tripping, and enjoying lazy beach days. Nature lovers will find the shoulder season ideal despite it being a bit complicated with the academic school year in Europe just starting, which means European tourists are still around in early September. However, by mid-September, the crowds begin to thin, and prices drop as family travelers pack up and return home.

Whether you are planning to enjoy swimming in the south or take advantage of the perfect hiking weather in the north, Spain in September has it all. Traveling during this time is a positive experience due to the many local festivals and holidays on the calendar. With the high summer temperatures beginning to abate, it is the ideal shoulder-season holiday for sunbathing, museum-hopping, and indulging in the eating and drinking culture that makes Spain a gastronomic marvel. My time in Spain during September was an unforgettable journey through a beautiful nation transitioning into the calm and cooler days of fall.


When I traveled to Spain last September, I was struck by how the weather varies significantly across this big country. In southern Spain, particularly Andalusia, the days were still hot both day and night, making it perfect for swimming and sunbathing. In contrast, the Costa Brava, Basque Country, Cantabria, and Galicia in the north began to cool off, offering warm days and chilly evenings. The temperature ranges were impressive; northern Spain saw lows around 60°F and highs up to 80°F, while the south experienced a hotter range from 70-90°F.

Despite a typical September having only a few rainy days, I packed a raincoat just in case, although the skies were mostly clear and sunny. The countrywide temperatures were generally warm, averaging between 77-82°F during the day and dropping to 68-72°F at night. The capital, Madrid, began to cool off from the brutal August heat with average highs of 79°F. Meanwhile, Barcelona was slower to cool, maintaining highs around 26°C.
