I’m wondering the same thing. Leaving SJPP on April 20 for my first Camino and will finish in Santiago. First night at Borda. I plan on starting to walk fairly early every morning. I’m from Florida so I run pretty cold. Anything under 70F I prefer to be in a long sleeve. I plan on bringing one of each of the following: lightweight merino t-shirt, lightweight merino 1/4 zip, mid weight fleece, Patagonia nano puff, rain jacket, rain pants, zip off hiking pants and leggings. That’s basically it as far as clothes. Does that sound like a good plan? I’m just wondering how hot it’s going to be on the meseta in early and mid May, but then may encounter colder weather in the higher elevations? Anyone have any insight into if that list of clothes sounds like a good plan?
