If you're walking the Spiritual Variant of the Camino Portugués in December, be ready for all kinds of weather. Past weather tells us that there could be sun, clouds, and rain. The trip starts in Tui and ends in Santiago de Compostela, and the weather will be normal for the Galicia area.
During your trip, it will probably be around 11° to 14°C in the day and around 6° to 7°C at night. This doesn't mean it will be the same every day though. There could be lots of sunny days, but there could also be lots of rain, from light showers to heavy downpours.
Galicia is famous for getting a lot of rain, especially near the end of the year, so expect some rain on your trip. The amount of rain might be anywhere from 3.4 mm/day to 7.5 mm/day.
