Climate Change Chart of Mykonos, Greece

Overview of climate changes

Temperature changes

The monthly mean temperature difference, averaged across calendar months, is an increase of +1.26 °C in the more recent period; this summarizes the set of monthly means rather than indicating that every month changed by the same amount. The largest monthly increase is in August, at +2.02 °C. These are changes in monthly averages, not daytime maximum temperatures.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, has a difference of -0.21 mm/day compared with the earlier reference period. This is an aggregate of monthly daily means, not a change in monthly rainfall totals, and it does not describe every month. The largest monthly decrease is in December, with a difference of -1.25 mm/day; by contrast, the largest monthly increase is in September, at +0.25 mm/day. The opposing monthly differences show why the overall mean should not be read as a uniform change throughout the year.

Changes in sunshine duration

Mean daily sunshine duration has an across-calendar-month difference of -0.08 hours/day. This unweighted mean describes the aggregate of monthly daily averages, not a change that applies equally to every month. The largest monthly decrease occurred in April, at -0.43 hours/day, while the largest monthly increase was in January, at +0.19 hours/day. These are differences in mean daily hours for the relevant months, rather than totals over each month.

Changes in snowfall

The mean daily snowfall difference, averaged across calendar months, is an increase of +0.01 mm/day. This small aggregate difference is based on monthly daily means and should not be taken to mean that snowfall increased in every month. The largest monthly increase is in January, with a difference of +0.09 mm/day; these figures describe mean daily amounts, not monthly snowfall totals.
