If you're planning a trip to Madrid in September, you should expect it to still feel like summer a lot of the time, especially at the beginning of the month. Daytime highs can rival those of August, but it cools down at night a bit more in September.
You'll find a handful of interesting annual events in Madrid in September. Music and movies top the list.
Madrid Weather in September
The afternoon highs in Madrid are 84 F on average, with lows reaching 57 F at night.
This feels like summer, no question about that. September brings six days that include rain, on average, and it's sunny the majority of the time, which adds to the summertime warmth.
What to Pack
For warm to hot days, pack lightweight everything: short-sleeved tees and shirts, lightweight pants or shorts, and capri pants for women. Jeans might feel a bit too warm in the daytime but would be a good addition for evenings after the sun goes down and things begin to cool off. You also might need a lightweight jacket or sweater for the evening. A poncho or pashmina adds some style for women out on the town. Take along comfortable sandals that are good for walking, boat shoes, and for women, a bit dressier sandals for evening. If you plan on visiting any churches, bring clothes that would be considered more conservative, such as skirts and modest tops for women. You cannot wear shorts or be scantily clad.
As far as accessories go, a hat and sunglasses are always a good idea. September is the driest month, so it's safe to leave your umbrella at home. Petty theft is common in Spain, so if possible, bring theft-proof clothes and clothes or bags with strong zippers.
September Events in Madrid
There aren't too many annual festivals and events in Madrid in September, but the few that are happening are great.
Also, it's the beginning of the fall arts season, which offers an abundance of art exhibits and performances.
DCODE Festival: One-day music festival on the Complutense University campus lasts 18 hours, from morning to night. Performers include Spanish and international stars in pop, rock, and indie genres.
Veranos de la Villa: You can catch the tail-end of this months-long festival if you are in Spain in the first two days of September; it runs from June 29 to Sept. 2, 2018. It's filled with an abundance of musical performances, flamenco, dance and performance art, and circus performances.
Cibeles de Cine: If you're a film buff, it's worth getting to Madrid early in September to catch this film festival, which runs from June 29 to Sept. 9, 2018. Classics and newer movies are on the schedule, which includes 90 titles in their original form with subtitles. So if you don't know Spanish, it's not a deal-killer.
Horse Racing: Get excited when your horse crosses the finish line at the Zarzuela Racecourse in Madrid. The races are run in the evenings in early September and then switch to mornings as the weather cools off later in the month.
September Travel Tips
As of January 2018, there was a travel warning for Spain because of the risk of terrorism.
September is a prime month for travel to Madrid, so it is smart to make reservations for your hotel as early as possible. When you're there, book a table at a restaurant and buy tickets to museums and shows in advance to avoid being disappointed or having a long wait at a restaurant.
Live on Spain's Schedule
Spaniards eat on the late side; they have lunch around 2:30 p.m. and dinner never much before 9 p.m. So don't show up at a restaurant expecting dinner at 7. And they party late into the night.
Beware of pickpockets anytime you are walking on the street. Take as little of value with you as possible and secure your wallet, passport, and any other valuables in a bag for that purpose or in front pockets that are more protected.
Women should carry crossbody bags that zip closed.
