Of course, you can do whatever you want,
but personally I would listen to those
who have walked more than one Camino and have more experience.
I was you on my first Camino.
I wanted to walk the VDLP in midsummer.
I knew it would be hot, but I grew up in the San Joaquin Valley and was used to 110 degree weather.
I figured I'd be fine.
Then there were a couple of folks who had done it and survived.
They said "Go for it!"
So we went.
A few days later we were having firemen bring us water because the fountains were dry
and we were in the middle of nowhere.
We could have easily died.
All because I didn't listen.
But I learned.
And you will too.
Being cold won't kill you.
But being warm sure will be a better experience.
One Camino doesn't give you experience - the conditions, including the weather, change from year to year.
Those of us who have walked many Caminos know it because we've experienced it.
Now I listen to THOSE people.
Just sayin'
