Santiago de Compostela is a Galician city of just over one hundred thousand people, and the figure depends on which INE operation you read: the padron gives 100,965 at 1 January 2025, the Censo Anual de Poblacion 100,842 at the same date. It sits in the province of A Coruna, so there is no Santiago province, and the provincial population and provincial asking price belong to A Coruna, which we cover separately.
The sharpest figure here is not INE's. IGE publishes a seasonal population load index, the taxa de carga poboacional, in full time equivalent persons; for the municipality in the third quarter of 2023 it reads 120.85, against 104.37 for the municipality of A Coruna and 105.89 for Galicia. It is a load index from a separate IGE operation, not a count of visitors or second homes, and it cannot be divided into or compared against an INE population.
Rain matters here. AEMET's normals for 1981 to 2010 come from Santiago de Compostela Aeropuerto, station 1428, at 370 m, a site Aena describes as lying in three municipalities: Santiago de Compostela, O Pino and Boqueixon. They give 1787 mm of rain a year, 139.5 days with 1 mm or more and 104.3 days of fog. Idealista prices five of the ten Santiago areas it lists in its July 2026 report.
The verdict
The upside is real. So is the downside. Both matter more than any brochure will admit.
Six service types in Adif's station listing
Adif lists AVE, Avant, Alvia, AVLO, Media Distancia and Regional at Santiago de Compostela-Daniel Castelao. That is what Adif publishes for the station, and it includes high speed.
An Aena airport with over three million users
Santiago-Rosalia de Castro handled 3,120,759 users in 2025 on Aena's own release. Aena describes the site as lying in three municipalities: Santiago de Compostela, O Pino and Boqueixon. Those are passenger movements, not tourists.
Hospital complex of its own health area
SERGAS places Santiago in the Area Sanitaria de Santiago de Compostela y Barbanza, whose hospital complex is the Complexo Hospitalario Universitario de Santiago, the CHUS. SERGAS publishes the complex portal itself.
The historic centre is not the dearest priced area
Of the five Santiago areas Idealista priced in July 2026, Casco Historico sits below the municipal figure and Ensanche - Sar sits highest. The usual assumption about old towns does not hold here.
Moderate summers in the AEMET normals
At the airport station the August average of daily maximum temperatures is 24.7 degrees and the annual mean is 13.0. AEMET's normals cover 1981 to 2010, and that August figure is an average, not a peak.
Wet and foggy through much of the year
The 1981 to 2010 normals give 1787 mm of rain, 139.5 days with 1 mm or more, 104.3 days of fog and 13.3 days of frost, from a station Aena places in three municipalities rather than in Santiago alone.
Half the listed areas carry no price
Idealista prices five of the ten Santiago areas it lists in its July 2026 report. Arins, Castineirino - Cruceiro do Sar, Conxo, Marrozos - Eixo and San Lazaro - Meixonfrio carry no figure at all.
Seasonal load runs well above the Galician figure
IGE's taxa de carga poboacional for the municipality reads 120.85 for the third quarter of 2023, against 105.89 for Galicia. It is a load index in full time equivalent persons, not a count of visitors or second homes.
One priced area fell over the year
Campus sur - Santa Marta stood lower in July 2026 than a year earlier on Idealista's own table, the only one of the five priced Santiago areas moving that way. All of these are asking prices, not sales.
Two gaps we could not fill
We have not been able to establish a Cercanias line inventory for Santiago, and the annual sunshine and cloudless day cells in the AEMET table are blank, so we publish no annual sunshine total for the station.
Editor's note
Santiago is a small city with a large seasonal load and a lot of rain, and both are sourced rather than impressionistic. What we cannot tell you is what the unpriced half of the city costs: Idealista prices five of the ten areas it lists, so Arins, Castineirino - Cruceiro do Sar, Conxo, Marrozos - Eixo and San Lazaro - Meixonfrio carry no figure, and there is no barrio tier below the district level here. Every Idealista figure is an asking price from advertised listings.
If the rain or the seasonal load puts you off, four other cities in this guide are worth reading next. A Coruna is in the same province, and Idealista prices twelve of the fifteen areas it lists there, so the coverage is better; its station has run from a provisional terminal since 14 December 2024. Valladolid has a Renfe Proximidad corridor rather than a Cercanias network. Toledo has one service type in Adif's listing, Avant from Madrid Puerta de Atocha. Salamanca gets neither an AVE nor an Avant in Adif's listing.
