Climate Change Chart of Prague, Czechia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.41 °C compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual figure, and it describes the aggregate rather than every month. The largest monthly increase was in January, with a difference of +5.40 °C; this refers to monthly mean temperature, not daytime highs.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of +0.19 mm/day compared with the earlier period. This unweighted average across monthly means describes typical daily amounts in aggregate, not monthly rainfall totals or a change shared by every month. The largest monthly increase was in August, at +0.72 mm/day, while the largest decrease was in April, at -0.41 mm/day. These contrasting monthly differences show why the aggregate should not be read as a uniform shift throughout the calendar year.

Changes in snowfall

Mean daily snowfall averaged across calendar months shows a difference of -0.29 mm/day compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual total, and it does not describe every month individually. The largest monthly decrease was in February, with a difference of -1.48 mm/day; the largest increase was in April, at +0.04 mm/day. The opposing monthly differences provide important context for the aggregate, while these averages alone do not indicate snowfall on particular days.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.06 hours/day compared with the earlier reference period. This unweighted mean of monthly averages summarizes the calendar-month pattern; it is not a day-weighted annual average and does not imply the same difference in each month. The largest increase occurred in July, at +0.75 hours/day, whereas the largest decrease occurred in January, at -0.80 hours/day. These monthly contrasts qualify the small aggregate difference rather than indicating a consistent change across all months.
