Well, I'm planning on April next year, which is spring. And we'll be heading north with the weather so the further north we go the cooler it was but the warmer it will become.
Mind you - it was 39 degrees (celsius) in Seville the week I was there. Although, surprisingly, it was very bearable heat. Any earlier than that we'll catch too much rain, I think.
HOWEVER - you do need to train, seriously, I think. The new friend with whom I walked part of the first stage has had to stop already and she was confident because of walking a lot at home.
It really gets to your feet unless you have proper preparation. Don't ignore the advice - or the signs....
ALSO - I'm not carrying a backpack. As I may have said, I've got a companion (donkey) to carry my baggage. It does make a difference when you don't have that extra weight to move.
Apparently there are some companies which will do it for you . Or - a shopping trolley's wheels are much bigger and better than a luggage trolley.
I'm going to be doing some walks with Jamilla (donkey) in and around London this summer, when i get her made, in case any 'tweaking' is necessary. (Too late when one's on the road.)
NB - with regard to the article you read; that's about the Camino Frances, across the north of Spain. That route is now very crowded, so I'm planning on the Via de la Plata, from Seville. Its a bit longer, but is flatter and although a lot of people are now doing it it's not as busy. Which means that the infrastructure is there but it hasn't yet become a circus.
