Overview of climate changes
Temperature changes
Averaged across calendar months, monthly mean temperature shows a difference of +0.70 °C compared with the earlier reference period; this is an unweighted average of monthly means, not a day-weighted annual figure or a measure of daytime maximum temperatures.

The largest monthly increase occurred in August, with a difference of +1.38 mm/day. In November, the largest monthly decrease was a difference of -0.50 mm/day. The opposing monthly changes help qualify the overall average: it does not imply that daily rainfall increased in every month.

Monthly changes differed: January had the largest increase, a difference of +1.38 mm/day, while December had the largest decrease, a difference of -1.51 mm/day. Those contrasting month-specific differences do not mean snowfall changed in the same direction throughout the year.
Changes in sunshine duration
Mean daily sunshine duration averaged across calendar months had a difference of -0.36 hours/day compared with the earlier period.
