Climate Change Chart of Sardinia, Italy

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.02 °C compared with the earlier reference period. This unweighted mean describes the aggregate of the monthly means, rather than a day-weighted annual average or the temperature in every individual month. The largest monthly increase is in December, with a difference of +2.16 °C. By contrast, May has the largest monthly decrease, a difference of -0.17 °C; these extrema show that the average change was not uniform across the months.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of +0.62 mm/day compared with the earlier reference period. This is an unweighted summary of the monthly means, not a monthly rainfall total, and it does not imply the same difference in every month. The largest monthly increase in mean daily rainfall occurs in November, with a difference of +1.92 mm/day. This describes the daily mean for that month, not the accumulated rainfall over the month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, has a difference of -0.23 hours/day compared with the earlier reference period. The figure is an unweighted mean of monthly means and should not be read as a change applying equally throughout the year. The largest monthly decrease is in November, with a difference of -0.72 hours/day hours per day; in February, the largest monthly increase is a difference of +0.24 hours/day. These monthly contrasts put the overall mean difference in context without implying a continuous change between the reference periods.

Changes in snowfall

Averaged across calendar months, mean daily snowfall has a difference of -0.10 mm/day compared with the earlier reference period. This unweighted summary describes the monthly means; it is not a monthly snowfall total, and the reported difference alone does not describe conditions in every month. The largest monthly decrease in mean daily snowfall is in February, with a difference of -0.52 mm/day. In April, the largest monthly increase is a difference of +0.17 mm/day, showing that monthly differences vary in direction.
