Clothing Guide for Your Spain Tour in September 

Most Regions in Spain: It’s still a bit hot in most regions in September, so dress in breathable clothing. Prepare short-sleeved t-shirts, shorts, skirts, dresses and sandals for your daytime outings. And you can wear long-sleeved t-shirts and long pants when the temperature drops sharply at night. If you want to stay warm from the cool nighttime sea breeze, a light coat or thin shawl will be helpful.

Northern & Northwestern Spain: Temperatures in northern and northwestern Spain are relatively low, so you need to dress warmly. Long-sleeved shirts, jeans, hoodies, and cardigans are suitable for the daytime. In addition, an outdoor jacket will keep you warm at night or on cloudy days. At the same time, because there are more natural landscapes in the north, a pair of comfortable sneakers will allow you to appreciate them without becoming too exhausted.

UV radiation in September cannot be ignored, sun protective clothing, sunscreen, sunhat and sunglasses are still required. In addition, please bring an umbrella in case it rains.
