Current Climate Climatology

This page presents Andorra's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit.  Other historical climatologies can be selected from the Time Period dropdown list. Data for  specific coordinates can be downloaded for in the Data Download page.

Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.

Climate Data Historical

Located in the middle of the central area of ​​the alpine bioregion of the Pyrenees, the climate of Andorra is a humid mountain climate of latitudes medium, but with Mediterranean influence in the southern sector, where the characteristics are of a continental Mediterranean climate. These conditions give rise to a range of distinct habitats that support a rich biodiversity, some species of which are unique or even endemic. Temperatures evolve from the temperature curves of the temperate zones of the northern hemisphere.

Temperature

  • Temperatures evolve according to the temperature of the northern hemisphere.
  • January is the coldest month of the year, with an average temperature of 0.3ºC and July the hottest with an average of 11.27ºC. 
  • Temperatures follow a very marked pattern by a negative annual mean gradient, varying from -0.4ºC / 100m for the months in which that the phenomena of thermal inversion are more present (October-January) down to -0.6º / 100 meters for the other months.

Precipitation

  • The most abundant precipitation occurs in summer (273 mm), then in autumn (259 mm), in spring (237 mm) and finally winter (181 mm).
  • Average precipitation is influenced by a first component described by a clearly marked longitudinal gradient that runs from the Atlantic (west) to the Mediterranean (east), and a secondary component defined by a highly differentiated positive altitudinal gradient between the Atlantic slope (mean +0.7 mm / 100m) and the Mediterranean basin (mean +19.8 mm / 100m), with a mean value for the Pyrenees of 11.5 mm / 100m.
