What should I pack for Argentina?
First and foremost: pack as lightly as possible!
Remember that you are guaranteed to come across things during the semester that you will want to take with you as souvenirs and give to friends and family. You should make sure to have space in your luggage to bring home memories from your time in Argentina.

Clothes
Generally, the temperatures in Buenos Aires are pleasant during both spring and autumn. However, early in the spring semester, one can still experience temperatures up to 40 degrees Celsius.
Early in the fall semester, it is relatively cool in Buenos Aires, but compared to Scandinavia, it is still considered summer.
The university does not have a dress code. If you are planning hiking or other special activities outside of Buenos Aires, you should pack what you need for this.
You should bring a cap or sunhat to protect yourself from the sun.
Bring a pair of wool socks for cooler nights, hiking, and excursions.

Toiletries
You can find most of the toiletries you might need in Buenos Aires. Bring any prescription medication you need. Bring earplugs if you are a light sleeper.
Other
Pack a towel. You can buy paper, pens, staplers, and so on in Buenos Aires.
Bring your laptop and textbooks.
