How Andorra’s climate is changing
Explore changes in temperature, precipitation, dry days and snow in Andorra using observations from Roc St. Pere and Sorteny.
Comparable years, specific questions
We compare completed years at Roc St. Pere since 1997. Trends require at least 95% valid days and 90% in every month for averages; totals and counts require the full year. To display frost counts with only one or two missing days, we use neighbouring minima if both are at least 2 °C from zero and on the same side. These counts are approximate; when uncertain, we show a range. We do not modify measurements or include these estimates in the trend or moving average.
Snow measured in the mountains
Andorra Recerca + Innovació’s BNA 2024–2025 provides 17 seasons at Sorteny, 2,290 m. Snow-cover days from November to April and dates above 30 cm describe natural snow at that location, not ski slope opening dates.
