Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of +0.88 mm/day in the more recent period.

August recorded the largest monthly increase in mean daily rainfall, with a difference of +2.78 mm/day compared with the earlier reference period. This identifies the strongest reported monthly increase, not a pattern shared by all months.

Changes in snowfall

The largest monthly decrease was in February, with a difference of -0.30 mm/day compared with the earlier reference period.
