Several times we have been talking with a local about “maybe it will rain” and they have said “It’s Asturias”. This seems to be an explanation for any weather. We have been in Asturias for nine days and it has rained on almost every one. But never all day, usually only a few times a day, and often in light spurts of 10-20 minutes.
We have not been bothered by the rain much at all. The biggest bother is taking our rain gear on and off so often. In general, on all our Caminos we have been pretty lucky with the rain, maybe 3 or 4 days total where it rained hard all day.
