Weather forecast for the Camino de Santiago Francés in September

September on the Camino Francés feels like late summer easing toward autumn. Many days are bright and warm, especially on the eastern half, but the pattern is changeable, with cloud building at times and passing showers. Short pulses of heavier rain are possible when fronts move through, more often in the mountains and in Galicia. Mornings tend to be fresh, afternoons comfortable to occasionally hot in the drier valleys, and evenings cool. As you progress west, the Atlantic influence grows: skies cloud over more often, drizzle becomes common, and temperatures soften. Overall it is a pleasant month for walking, with a fair sun–cloud mix and intermittent wet spells.

Navarre

From the Pyrenees into the Navarrese valleys, the month often starts with low cloud and patchy drizzle clinging to the hills, then breaks into brighter spells as you descend. Through the valleys the pattern is mostly dry with long sunny stretches, but brief showers or a thundery burst can sweep through without much warning. Temperatures follow a cool-start, warm-to-hot afternoon pattern.

La Rioja

Crossing into La Rioja, the weather settles into clearer, drier days with plenty of sun over the vineyards. Isolated showers or a short-lived band of rain can develop, yet they usually pass quickly and many days stay fine. Afternoons are generally warm, with a summery feel.

Castile and León

Beyond Burgos and across the meseta, skies alternate between wide blue and hazy overcast, and long dry runs are normal. Passing disturbances still bring light showers and occasionally a more persistent, soaking spell, while nights cool off notably under clear skies. Closer to the Montes de León and into El Bierzo, the air turns fresher, clouds thicken more often, and showery days become more frequent; overall it feels mild to warm.

Galicia

Climbing into Galicia over O Cebreiro, the Atlantic takes over with frequent cloud, mist on the ridges, and drizzle or steady rain at times. Breaks of sunshine appear between systems, but the balance tilts to more cloud than blue skies. Through the last valleys to Santiago the pattern stays changeable, with many damp days and the occasional heavy downpour; temperatures sit in a cool-to-mild range.
