Climate Change Chart of Bodø, Norway

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.76 °C in the more recent reference period; this unweighted mean describes the set of monthly averages, not a day-weighted annual figure or a change in daytime maximum temperatures. The largest monthly increase was in February, with a difference of +3.36 °C compared with the earlier period. This identifies the strongest increase among the supplied monthly comparisons, rather than implying that every month warmed by the same amount.

Changes in snowfall

Mean daily snowfall averaged across calendar months had a difference of -1.00 mm/day in the more recent period. This unweighted comparison of monthly means is not a monthly snowfall total, and it summarizes the aggregate rather than every month individually. The largest monthly decrease in mean daily snowfall occurred in February, with a difference of -5.78 mm/day. In December, the largest monthly increase was a difference of +1.78 mm/day, illustrating that the direction and size of the monthly differences varied.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months shows a difference of -0.45 hours/day between the reference periods. This unweighted summary concerns monthly means, rather than a day-weighted annual measure. The largest monthly decrease was in May, where the difference was -1.92 hours/day. In October, sunshine instead recorded the largest monthly increase, with a difference of +0.26 hours/day; neither comparison means that daily sunshine changed uniformly throughout the month.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of +0.67 mm/day in the more recent period. This is an unweighted comparison of monthly means, not an annual rainfall total or a day-weighted average. The largest monthly increase in mean daily rainfall occurred in February, with a difference of +1.28 mm/day. By contrast, October had the largest monthly decrease, a difference of -0.05 mm/day; these monthly shifts do not describe every day within either month.
