Portugal and Spain - what wetsuit?

Hi all,
Traveling with entire family to Europe and intend to catch a surf session on Portugal central coast and close to Barcelona. Don't currently own a 3/2 long and trying to travel light. How do you think a 2/1 spring suit holds up? I have a 4/3, but again, trying to travel light.
During the Summer in SoCal I can trunk it with a 0.5mm neoprene rashguard, or wear the spring suit.
Otherwise I need to bring the 4/3. Renting the suit is probably not a good idea.
Where should I plan to surf in Portugal? Peniche area? I will need to rent a board.
BTW, is their consistent surf next to Barcelona (or even a couple hours away) during the summer? I will stay 3 weeks so might be able to go to a few different spots, even farther (San Sebastián?)
I speak Portuguese and Spanish.
Thanks
