Climate Change Chart of Crete, Greece

Overview of climate changes

Temperature changes

Averaged across calendar months, the difference in monthly mean temperature was +0.26 °C; this unweighted mean summarizes the monthly averages rather than a day-weighted annual measure, and it does not imply that every month warmed. The largest monthly increase was in January, at a difference of +0.93 °C. The largest monthly decrease was in June, with a difference of -1.01 °C. These are changes in monthly mean temperatures, not daytime maximum temperatures, and the contrasting monthly differences show why the overall mean should not be read as a uniform change through the calendar.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +0.37 mm/day. This is an unweighted mean of monthly daily averages, not an annual total or a day-weighted average, and does not mean that rainfall increased in every month. The largest monthly increase occurred in February, where the difference in mean daily rainfall was +1.13 mm/day. These figures describe daily mean amounts within the monthly comparison, not monthly rainfall totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.23 hours/day. This unweighted summary of monthly daily averages does not indicate the same change in each month. The largest monthly decrease was in February, with a difference of -0.64 hours/day hours per day; by contrast, the largest monthly increase was in November, at a difference of +0.02 hours/day hours per day. These monthly differences describe average daily sunshine, not total hours for the month.

Changes in snowfall

Averaged across calendar months, mean daily snowfall had a difference of +0.06 mm/day. This is an unweighted average of monthly daily means, not a day-weighted annual amount, and the small mean difference should not be taken to mean snowfall was absent. The largest monthly increase was in February, where mean daily snowfall had a difference of +0.49 mm/day. This refers to a daily mean amount for that month, not a monthly snowfall total.
