Camino del Norte
Weather in September

Weather Overview

September on the Camino del Norte offers mild daytime temperatures ranging from 17 to 29 degrees Celsius, though conditions cool noticeably as you progress eastward from the Basque Country. The Basque region near the start averages around 25 degrees during the day, but by the time you reach Cantabria and Asturias, expect temperatures closer to 21 to 22 degrees. Nights are consistently cool across the entire route, dropping to between 11 and 18 degrees, so layering remains essential even when daytime warmth tempts you to pack light.

Rainfall is the defining feature of this northern coastal route. You should anticipate wet weather on roughly six to nine days out of every ten stages, with Cantabria and Galicia particularly prone to persistent rain. The precipitation comes frequently but typically in light to moderate showers rather than all-day deluges, though total rainfall averages 165 millimetres. Wind gusts regularly reach 53 kilometres per hour, especially on exposed coastal sections and ridgelines where conditions can feel considerably more challenging than temperatures alone suggest.

Elevation gains and losses total around 1043 metres and 809 metres respectively, with the highest point at Sobrado reaching 504 metres. Higher passes bring noticeably colder nights and increased wind exposure. Start your walking days early to complete major climbs before afternoon weather deteriorates, and carry reliable waterproof layers throughout the journey—dry clothing will matter more to your comfort here than any other single factor.
