July and August offer the best weather for visiting Santiago de Compostela, with warm temperatures averaging 25C (77F), just 6-7 rain days per month, and 8-9 hours of daily sunshine. But the best overall time depends on what you are optimizing for. If you want to see the cathedral during the Apostle Festival (July 24-25), book accommodations 6 months ahead. If you prefer lower prices and fewer crowds, aim for May, June, or September. The worst months for weather are November through February, when rain falls on 14-17 days per month and sunshine drops to 3 hours daily.

Best Time to Visit Santiago de Compostela for Good Weather
July and August are the clear winners for weather. You will get the warmest temperatures (23-25C / 73-77F highs), the least rain (35-50mm monthly), and the most sun (8-9 hours daily). June is close behind with highs of 23C (73F) and only 57mm of rain. September still delivers good weather with highs of 23C (73F) but rainfall jumps to 93mm. If you want to combine decent weather with smaller crowds, target the second half of June or the first two weeks of September. These shoulder windows give you 70-80% of peak summer conditions with noticeably thinner crowds at the cathedral and around the Praza do Obradoiro.

Best Time to Visit Santiago de Compostela to Avoid Crowds
The cathedral receives over 300,000 visitors annually, with the heaviest crowds concentrated in July and August. For the lowest crowds, visit in November, January, or February. These winter months see far fewer tourists and pilgrims, though you will trade crowds for rain and short daylight hours. The sweet spot for moderate crowds and acceptable weather is May and October. In May, you get 20C (68F) highs and 7 hours of sun, but the summer crush has not yet arrived. October brings autumn colors and thinning crowds after the September shoulder, though rainfall is heavy at 165mm. Avoid the two weeks around July 25 (Feast of St. James) unless you specifically want to experience the festival atmosphere with packed plazas and fully booked hotels.

Best Time to Visit Santiago de Compostela for Lower Prices
Hotel rates in Santiago de Compostela follow a predictable seasonal curve. Prices peak in July and August at roughly 120-180 euros/night for a mid-range double room near the old town. They drop 30-40% in November through February (excluding Christmas week), when the same room runs 60-90 euros/night. The Parador de Santiago (Hostal dos Reis Catolicos), the city’s iconic luxury hotel, ranges from 180 euros/night in January to over 350 euros/night in July. For the best value, book for May or October. You will pay roughly 20% less than peak summer rates while still getting reasonable weather. Airfares to Santiago de Compostela Airport (SCQ) follow the same pattern, with Ryanair and Vueling offering their lowest Galicia fares in late autumn and winter.

Best Time to Visit Santiago de Compostela for Festivals and Events
The Feast of St. James (Festas do Apostolo) on July 24-25 is the city’s defining celebration, drawing pilgrims from around the world for a multi-day program of concerts, fireworks, and the famous cathedral light show. May hosts the Festa da Ascension, typically the second week of the month, with Galician folk music, traditional markets, and free concerts in the Alameda park. August 16 brings the Festas de San Roque, a smaller but lively neighborhood festival with street processions and food stalls. If you are planning a trip around a specific event, book accommodation 4-6 months in advance for the Apostle Festival and 2-3 months for Ascension. For a quieter visit that still catches local culture, time your trip for the first week of July (between Ascension and the Apostle Festival) when the city is festive but not overwhelmed. For more details, see our Santiago de Compostela travel tips.
Worst Time to Visit Santiago de Compostela
November and December are the least favorable months. You will face 159-174mm of monthly rainfall, only 3 hours of daily sun, and short daylight (sunset around 18:00 in November, 17:30 in December). Many outdoor cafes close their terraces, and the stone streets stay perpetually damp. January and February are slightly better for rain (118-157mm) but remain cold and gray. If your schedule forces a winter visit, focus on indoor attractions: the cathedral museum (12 euros, open daily), the Museo do Pobo Galego (4 euros, closed Mondays), and the city’s excellent restaurants serving caldo gallego (Galician soup, around 5-8 euros per bowl) and pulpo a feira (octopus, roughly 12-15 euros per portion). The Christmas lights and markets in December add some cheer, but do not expect postcard weather. For more details, see our Santiago de Compostela weather by month guide.
