October on the Camino Portugués de la Costa offers moderate temperatures, with highs typically ranging from 18°C to 31°C, and lows hovering between 4°C to 20°C. The weather fluctuates between sunny days and periods of moderate rain, reflecting the Atlantic influence. While patches of rain may occur, many days are pleasantly sunny, making the coastal route vibrant with possibilities. Hikers should be prepared for sudden showers amidst otherwise clear conditions, as the coastal influence keeps the weather dynamic throughout the month.
Starting in Porto, autumnal conditions prevail with temperatures often rising to 31°C on some of the warmer days, punctuated by cooler nights dropping to 11°C. The region experiences a mix of sunny days and intermittent rain showers, with precipitation occasionally spiking but generally remaining moderate. Moving north through Labruge and Póvoa de Varzim, expect similar weather patterns with short-lived but heavy downpours, followed by brighter spells, creating a dynamic weather landscape typical of this coastal area.
As hikers progress toward Marinhas and Viana do Castelo, the weather stabilizes slightly with sunny interludes becoming more frequent. Though some heavy showers do occur, they are interspersed with long periods of sun, particularly as you head towards Caminha.
Crossing into Galicia towards Porto Mougás, the weather remains varied, with sunny days interlaced with periods of rain. Coastal breezes keep temperatures relatively mild, peaking at 26°C, and lows dipping to around 10°C on cooler nights. A Ramallosa and Vigo see similar alternating weather, as heavy rain showers can briefly interrupt otherwise sunny conditions.
Entering the final stages near Redondela and Pontevedra, the area experiences more frequent bouts of rain, though sunny days are still common. Mild temperatures persist, offering a favorable climate for hiking.
In the concluding stages from Caldas de Reis to Santiago de Compostela, expect both sunny intervals and overcast days with sporadic rain showers. The transition from coastal to more sheltered inland areas gives rise to cooler nights and a chance of fog, especially approaching Santiago, yet the journey ends with a rewarding climate characterized by Galicia’s unique charm.
