Welcome Ken, I hope to give you some insight as I walked the Camino this past Sept/Oct. I started Sept 3 from SJPdP and arrived in Santiago Oct 6. I walked 33 days with one rest day: 34 days total. I used the
Brierley guide and followed the stages until Leon. I decided to pass through Leon and stay off stage at Le Virgin del Camino, by doing this I was able to avoid the main crowd for 4 or 5 days until getting back to the stages at Villafranca.
Accommodations: There were a lot of pilgrims throughout but I was always able to get a bed partly because I traveled solo and I started my day no later than 6:30am. This is the schedule I fell into and was comfortable with.
Weather: In the beginning we had clear blue skies, it was warm/hot during the day and cool in the morning/night. Morning of day 6 started out in the rain, but didn't last long. We had several days of cloud cover which made for a nice umbrella from the hot sun. Really good weather for the next 20 days sunny, warm/hot, some cold mornings. Day 26: I believe we are getting close to Galicia as there is wind and some rain, cooler weather. Nearing Santiago with clear blue skies for the next 7/8 days. Including clear blue skies for my trip to the sea. I was truly blessed with great weather, for me it was the best type of weather for taking a long walk.
Scenery: The mountains were green and the farm land still rich in color. The wheat fields had just been harvested so they were golden brown. It was all so breathtaking. There were low lying clouds running through the valleys and rays of sunshine kissing the sunflowers. It's so hard to describe what I can see clearly in my mind. You will have to see for yourself but until you do I've attached a few teasers for you. Enjoy!
No matter when you go, you'll go when the time is right and the Camino will provide.
Peace be with you and may the Lord guide your steps.
