The issue is that we are all different and consider “nice weather” different weather forecasts. Most popular times to go to the Camino are Spring and Autumn but bear in mind that this is the North of Spain and the weather is unpredictable, you can have really wet summers and lovely sunny autumn days.
In terms of crowds, May & September are the busiest months, so if you’d like to walk with a level of peace and quiet, we recommend you walking in a different time.
