Do I need a jacket today in Lisbon, Portugal?

Question

Accepted Answer

Light jacket. Big temperature swing, make sure you have a light jacket. For this guide, a jacket can mean either a light jacket or a heavier outer layer. A light jacket often feels comfortable around 50-65°F, while a warmer jacket may make sense around 35-50°F. If the clothing recommendation says long sleeves or a light jacket, a thin jacket may be enough; if it says heavy coat, treat that as a warmer jacket or coat decision. Closed-toe shoes are usually better than sandals or flip flops in jacket weather because they help retain warmth.
