Climate Change Chart of Anticipate, Latvia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.22 °C compared with the earlier reference period. This is an unweighted mean of monthly means, not a day-weighted annual average, and it describes the overall monthly pattern rather than every month or daytime maximum temperatures. The largest monthly increase was in January, with a difference of +4.36 °C; that identifies the strongest increase, not a uniform change across the year.

Changes in snowfall

Mean daily snowfall averaged across calendar months shows a difference of -0.25 mm/day compared with the earlier reference period; this is an unweighted average of monthly means, not an annual total. Monthly changes varied: the largest decrease was in January, with a difference of -1.44 mm/day, while the largest increase occurred in November, at a difference of +0.75 mm/day. These daily-mean differences describe changes in the monthly averages and do not indicate the amount accumulated over a month.

Changes in rainfall

Mean daily rainfall, rather than monthly rainfall totals, was higher on average across calendar months, with a difference of +0.27 mm/day. This unweighted mean summarizes the set of monthly means and does not imply that rainfall increased in every month. The largest monthly increase occurred in October, at a difference of +1.03 mm/day, while April recorded the largest decrease, a difference of -0.12 mm/day. These contrasting monthly changes show why the average should not be read as a description of each month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months shows a difference of 0.00 hours/day at the displayed precision between the reference periods. This rounded, unweighted mean does not establish that sunshine was unchanged in every month. The clearest opposing monthly differences were in June, where the largest increase was +0.63 hours/day, and October, where the largest decrease was -0.74 hours/day. These are differences in mean daily hours, not total sunshine accumulated over a month.
