Hello Eamo, I walked the same camino in 2016. Very comfortable temperatures seldom requiring a jacket or pullover. Occasional light fog in the mornings. No rain all the way to Fisterra. Some days were a bit too warm on the interior sections. Pack some snacks as many of the coastal bars you pass will be closed for the season after Sept 15 or only open certain times and days. Take adavantage when you do come across one that is open. It is a beautiful camino. Don't be afraid to get off the official route if something looks interesting. For example, in Baiona the official route keeps you in back lanes and takes you away from the waterfront streets of one of the best towns on the route. Head down to the waterfront streets and enjoy. Great area to take a rest day if you have the time. Also the fellow running campground/albergue at O'Muino knows every inch of every route and will give you some very good advice. Also serves a great breakfast. Bom Camino
