I drive back and forth from Santiago to Ribadeo yesterday, and there was not a cloud in the sky. These last few days are the first of the season with over 30c temperatures, so hat and sunblock would be required.
I am just back in the U.K. after 5 weeks on the Way from Santander, on the Norte and Primitivo. Weather wise I got lucky and only had 3 days which could be called 'WET'. In other words I had poncho and trousers on all day. Other days had some wet times but mostly in the afternoon and evenings. Best advice would be 'get up and get on' especially in the mountains where there is often a change in the late afternoon.
Take care and don't hurry! The world can wait, it is you and the Camino that are important!
