If you plan to walk the Spiritual Variant of the Camino Portugués in June, you might see both sunny days and cloudy days. You might also have some rain, and sometimes it might be heavy, so you should be ready for changing weather.
The weather will get a bit colder as you walk north, in places like O Porriño and Arcade. You should expect the day's highest temperature to be around 22°C at first. But when you near Santiago de Compostela, the day's high will be closer to 19°C. The lowest temperature in the night will fluctuate between 10°C and 13°C throughout the trip.
The amount of rainfall will also change as you walk. Areas at the beginning of your journey, like Tui and Arcade, will see less rain, averaging less than 2mm/day. However, as you continue, you might see more rain, especially when you near cities like Vilanova de Arousa and Santiago de Compostela. Rainfall can reach up to 8.6mm/day and 7.8mm/day in these areas.
In simple words, during June, the Spiritual Variant of the Camino Portugués can have sunny, cloudy, and rainy days, but the temperature is mostly comfortable. However, you should be ready for more rain in the later stages of your trip.
