Overview of climate changes
Temperature changes
Averaged across calendar months, monthly mean temperature showed a difference of +1.37 °C between the periods; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime highs. The largest monthly increase was in January, with a difference of +5.10 °C. In contrast, August recorded the largest monthly decrease, a difference of -0.25 °C. These monthly contrasts show that the overall mean difference does not describe every month equally.
Changes in sunshine duration
Mean daily sunshine duration decreased by a difference of -0.50 hours/day when averaged across calendar months, using an unweighted mean rather than a day-weighted annual average. The largest monthly decrease was in May, with a difference of -1.55 hours/day. By comparison, April had a small increase, a difference of +0.18 hours/day. The overall decrease therefore does not imply that sunshine duration fell in every month.
Changes in rainfall
Mean daily rainfall, rather than monthly rainfall totals, had an average difference across calendar months of +0.58 mm/day; this is an unweighted mean of monthly conditions, not a day-weighted annual figure. The largest monthly increase occurred in September, where the difference was +1.36 mm/day. August moved in the opposite direction, with the largest monthly decrease: a difference of -0.48 mm/day. These monthly shifts indicate why the mean should be read as an aggregate, rather than as a change shared by every month.
Changes in snowfall
Mean daily snowfall showed an average difference across calendar months of +0.72 mm/day; this is not a monthly total or a day-weighted annual average. The largest monthly increase occurred in March, with a difference of +4.09 mm/day, while November had the largest monthly decrease, a difference of -3.05 mm/day. The opposing monthly changes qualify the overall mean: it summarizes the months collectively and does not indicate the same shift in each one.
