Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of -0.45 °C; this is an unweighted average of the monthly means, not a day-weighted annual figure or a measure of daytime maximum temperatures. The largest monthly decrease was in May, with a difference of -2.77 °C. By contrast, October had the largest monthly increase, a difference of +1.27 °C; these are the two most pronounced monthly shifts, not evidence that every month changed in the same direction.

Changes in rainfall

For mean daily rainfall, the difference averaged across calendar months was -0.06 mm/day. This summarizes unweighted monthly means, rather than monthly rainfall totals or a day-weighted annual average. The largest monthly increase occurred in June, at a difference of +1.27 mm/day, while August recorded the largest monthly decrease, at a difference of -1.78 mm/day. These daily-mean changes describe monthly averages and do not establish how rainfall varied from day to day.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.11 hours/day. The figure summarizes unweighted calendar-month means, not a day-weighted annual average. The largest monthly increase was in August, with a difference of +1.42 hours/day; the largest monthly decrease was in June, with a difference of -1.01 hours/day. These shifts concern average daily sunshine duration within the named months and do not describe every day.
