Every year, millions of Spaniards ask the same question as December arrives: will it snow at Christmas? The image of a snowy Christmas Eve is part of the collective imagination, but the meteorological reality in Spain is far more varied. Let us review the historical statistics to find out what to expect between December 24 and 31.

A "white Christmas" in Spain: myth or reality?

Across most of Spain, a Christmas with snow at low elevations is an uncommon event. The probability of snow on Christmas Eve or Christmas Day at sea level is below 2 % in almost every provincial capital. However, in mountain areas the picture changes dramatically:

  • Pyrenees (above 1500 m): snow probability at Christmas exceeds 70 %. Resorts like Baqueira-Beret and Formigal usually have good snow cover.
  • Cantabrian Range (above 1200 m): 50-60 % probability. San Isidro and Alto Campoo typically have snow.
  • Central System (above 1800 m): 40-50 %. Navacerrada may have snow, but Madrid city rarely sees it.
  • Sierra Nevada (above 2000 m): 60-70 %. The ski resort is usually open at Christmas.

Average temperatures from December 24 to 31

Temperatures in the last week of December vary enormously by region:

  • Madrid: average high 9-11 °C, low 1-3 °C. Frost is common on clear nights.
  • Barcelona: high 13-14 °C, low 5-7 °C. Milder thanks to Mediterranean influence.
  • Seville: high 15-17 °C, low 5-7 °C. Sunny days can reach 18 °C.
  • Bilbao: high 12-13 °C, low 5-7 °C. High probability of rain.
  • Zaragoza: high 9-11 °C, low 1-3 °C. Persistent fogs in the Ebro valley.
  • Valencia: high 15-16 °C, low 6-8 °C. Mild climate with frequent sunshine.
  • Las Palmas: high 22-23 °C, low 16-17 °C. Christmas in short sleeves.

Typical December weather phenomena

Besides potential snow, December brings other phenomena that can affect Christmas travel:

  • Valley fog: the Ebro valley, the northern plateau and river basins are prone to persistent fog that can reduce visibility to under 100 metres and last all day.
  • Atlantic storms: fronts from the Atlantic can bring heavy rain to Galicia, Asturias and the western seaboard, with wind gusts exceeding 100 km/h.
  • Inland frost: clear, calm nights promote radiation frost that can push temperatures to -5 or -10 °C on the northern plateau.
