What is the weather like in Cantabria, Spain in October usually.?
Unless you are very very warm blooded, leave the shorts at home! Whilst the weather in October in Cantabria should be pleasant, it won’t be beach weather! Doubtful that you would be walking around in a t-shirt. You won’t need winter clothes, but certainly a jacket for the evenings. Expect temperatures around 15C – 20C…but at the end of October a tad chillier.
