Climate Change Chart of Andorra la Vella, Andorra

Overview of climate changes

Temperature changes

The monthly mean temperature difference averaged across calendar months was +1.53 °C in the more recent period; this is an unweighted average of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in December, at a difference of +4.57 °C, while April had the largest decrease, a difference of -0.01 °C. These month-specific contrasts describe the two reference periods, not a continuous change between them.

Changes in snowfall

Mean daily snowfall averaged a difference of +1.75 mm/day across calendar months; this is an unweighted average of monthly means, not a monthly total or day-weighted annual amount. The largest monthly increase was in March, with a difference of +5.98 mm/day. These period comparisons describe recorded snowfall averages and do not establish that every month changed in the same way.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, averaged a difference of +0.42 mm/day across calendar months between the reference periods. That unweighted average summarizes monthly means and does not imply that rainfall increased in every month. The largest monthly increase occurred in November, with a difference of +1.17 mm/day; in March, the largest decrease was a difference of -0.30 mm/day.

Changes in sunshine duration

Mean daily sunshine duration averaged a difference of -0.37 hours/day across calendar months, an unweighted summary of the monthly means rather than a day-weighted annual figure. The largest monthly decrease was in November, with a difference of -0.73 hours/day; this marks the strongest decrease among the reported monthly differences, not a uniform change across all months.
