Traveller notes on Santiago de Compostela in October
Other months in Santiago de Compostela
Regulars are blunt that no matter which month a trip lands on here, some rain is genuinely likely - this city's reputation for grey, wet weather holds even in the better stretches - though the last two weeks of this month specifically get named as one of the better windows before deep summer. Our row backs that mild, genuinely wet read, 21.2C over 10.1C nights feeling 8C, with 90.2mm of rain across 10.6 days and humidity at 82 percent. Regulars are consistent that sunny days do arrive in real number even within a rainy month, layering being the standard approach for Camino walkers rather than betting on either extreme. Shorts versus long trousers debates among Camino hikers reflect just how variable a single day here can run. The record: 11 hours of sun, an 18.6 kph wind and AQI 35.
Regulars call this a good time to arrive specifically because it's cooler and quieter than peak summer, with the first part of the month often still holding sunny, almost-summer conditions before any real change sets in. Our row backs that transitional read, 23.6C reading as 24C over 13C nights, with 78.2mm of rain across 8.5 days. Regulars note genuine year-to-year swings on top of the average - one especially hot September ran 30-35C with the season's first rain arriving only in the final days of the month - a reminder that this destination's Atlantic-influenced weather doesn't repeat identically every year. The record: humidity 81 percent, 9.8 hours of sun, a 17.8 kph wind and one of the cleanest air readings in this project, AQI 34.
Santiago de Compostela-forum threads on March weather are direct that Galician spring runs genuinely rainy, posters warning newcomers to come prepared for a real amount of rain rather than hoping for a dry week. Conditions are called unpredictable day to day, a clear morning just as likely to turn wet by afternoon as the reverse. Anyone walking the Camino Frances into town this time of year gets a specific warning: snow is a real possibility at higher elevations along the route, including around O Cebreiro, even when the city itself stays free of it. The standing packing list across every thread is the same - a proper lightweight rain jacket, a warm jumper, and quick-drying trousers rather than anything that stays wet once soaked. Regulars call the payoff thinner crowds than the peak Camino season just ahead. The record: 15.2C days feeling like 13C, 5.9C nights, a notably high 165mm across 14.5 days, 0.1cm of high-elevation snowfall, 84 percent humidity and 8.2 hours of sun.
June is the month most people name for walking the Camino into Santiago - the chance of good weather is at its best, and neither the path nor the beds are yet crowded - but Galician regulars attach the same caveat to every month of the year: you will probably meet rain whatever you do. June to August is the driest stretch and still gives our row 75.5mm across 9.3 precipitation days at 83 percent humidity. Their description of a June week is beautiful sun at 20 to 25C interrupted by a genuinely wet, windy day, occasionally with hail. So: a jacket or pullover for chilly nights and a small umbrella, always. The record: 23C days, 12.8C nights and 11.2 hours of sun.
