Climate Change Chart of Rethymno, Greece

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperatures show a difference of +0.54 °C. This is an unweighted comparison of monthly averages, not a day-weighted annual mean, and it describes the aggregate rather than every month. The largest monthly increase was in December, with a difference of +1.95 °C; by contrast, June had the largest monthly decrease, a difference of -1.50 °C. These are monthly mean temperatures, not daytime maxima.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +0.64 mm/day. This unweighted mean difference describes the broad monthly-average comparison, not a change in every month, and the figures are daily means rather than monthly totals. The largest monthly increase occurred in February, where mean daily rainfall had a difference of +1.74 mm/day; that monthly contrast is more specific than the across-month average and should not be read as a year-round pattern.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.31 hours/day. This is an unweighted comparison of monthly means, not a day-weighted annual measure, so it does not imply the same change in each month. The largest monthly decrease was in February, with a difference of -0.80 hours/day hours per day. Together, these figures describe the overall monthly-average difference and the most pronounced monthly decrease, rather than a continuous change between the reference periods.

Changes in snowfall

Mean daily snowfall averaged across calendar months had a difference of +0.05 mm/day. This unweighted comparison is based on monthly averages, not day-weighted annual snowfall or monthly totals, and the small difference should be understood at the displayed precision rather than as evidence that snowfall was absent. The largest monthly increase occurred in January, with a difference of +0.32 mm/day in mean daily snowfall. The across-month mean and this month-specific contrast describe different scales of comparison.
