Posted this before on another thread but the month and weather info is in it!
Hi!
I walked from Porto to Santiago along the Coastal, Senda Litoral and Variant Espiritual from Sept 20th till 13 October 2021!
Average temp after a cool start was between 20 and 27 C with one day of heavy rain near Redondela! (temp was 22C)
The 27 degree day was on the 12th October in Santiago.
There were enough pilgrims for socialising but you could still walk alone along the way if you wished !
That is until Vigo onwards when the numbers increased as you were in the last 100km to Santiago.
Beaches were empty but still places to eat and no problem with accommodation.
I would add to any reply about the Coastal; walk out along the Douro River nice and easy.
Secondly if you get the chance do the Espiritual from just north of Pontevedra (easy to find the start) it's wonderful; visit Combarro, Armentiera (stay in the Monastery) and the Pilgrim boat from Villanova de Arousa best bit of the Camino loved it will do it again one day!
No bets on the weather might be raining who knows!!!
I hope it's as good for you when you walk
Buen Camino
