Changes in rainfall
Mean daily rainfall, rather than monthly rainfall totals, had an unweighted across-calendar-month mean difference of -0.34 mm/day. This summarizes the monthly means and does not describe the change in every month. The largest monthly decrease was in September, a difference of -2.03 mm/day in mean daily rainfall; by contrast, June had the largest monthly increase, with a difference of +0.36 mm/day. These mark contrasting monthly changes, not a uniform shift across the year.
Changes in sunshine duration
