Hope someone who lives or has lived in Barcelona speaks up.
I found this: weather in november, 2004
http://www.barcelona-tourist-guide.com/weather/weather-november.html Sounds like layering + travel fold up raincoat.
Barcelona's metro+train system will prove quite useful.
And passes And buses.
That's all we had to get around. And wished we had
more time; it was all so easy and efficient.
All we had were 6 short days.
The tourist info at Plaza Cataluña was very helpful on
all kinds of transport tips, maps,approaches etc.
There are many interesting towns. Girona is lovely and doesn't depend on the beach scene to make it interesting.
I do wonder how cold those beach winds get come November.
There is,of course, the jaunt to Dali's Teatro Museo in Figueres and the charming Gaudi church in Colonial Guell. Tarragona.
Also we had so much to do that we didn't even come
close to taking advantage of all the theater + performance venues.Check events. concerts.
Have you checked for November
regional fiestas as well?
Festival Internacional de Jazz de Barcelona take place
in Nov.
There were outlying areas around Barcelona that sounded interesting but... we didn't have the time. I will be curious what you turn up. Happy hunting
