Rain, rain, and more rain – take this into account, especially if you get as far North West as Santiago de Compostela – here your expected high is around 52°F (11°C) and your expected low is 46°F (8°C). If you’re visiting without an umbrella throughout this month, you’ll be changing outfits at least twice a day – not to mention the laundry you’ll be doing. Plan accordingly, the rain can be lovely, but as always: the rain can be wet!
