Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.60 °C compared with the earlier reference period; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime highs. The monthly pattern was not uniform: November had the largest increase, a difference of +1.29 °C, while April recorded the largest decrease, a difference of -0.19 °C. These extrema describe the identified months and do not imply that every month followed the same direction.

Changes in rainfall

Mean daily rainfall, rather than monthly totals, was higher on average across calendar months, with a difference of +1.39 mm/day. This is an unweighted comparison of monthly means, so it does not describe the amount of rain falling over a full year or imply that each month was wetter. The clearest monthly increase was in August, at a difference of +4.65 mm/day; by contrast, June showed the largest decrease, a difference of -0.31 mm/day. The opposing monthly differences underline that the overall mean does not represent every month's change.

Changes in sunshine duration

Mean daily sunshine duration was lower on average across calendar months, with a difference of -0.72 hours/day compared with the earlier reference period. This unweighted mean summarizes monthly averages; it is not a day-weighted annual figure and does not mean that sunshine declined in every month. The largest monthly decrease occurred in March, with a difference of -1.49 hours/day, while June had the largest increase, a difference of +0.16 hours/day. These monthly contrasts help qualify the overall mean without suggesting a uniform pattern throughout the year.

Changes in snowfall

For mean daily snowfall, the unweighted average across calendar-month means is unchanged at the displayed precision: a difference of 0.00 mm/day. This rounded comparison does not establish that snowfall was absent, nor does it rule out differences smaller than the displayed precision; it describes the aggregate monthly means rather than monthly totals or conditions in every month.
