Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of +3.64 mm/day in the more recent period. This unweighted average describes the set of monthly means; it is not a day-weighted annual average or a monthly rainfall total. The largest monthly increase in mean daily rainfall occurred in April, with a difference of +9.83 mm/day. This identifies the strongest monthly increase in the supplied comparison, not a change in monthly totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of +0.45 hours/day compared with the earlier reference period. This is an unweighted average of monthly means, rather than a day-weighted annual figure, and does not imply the same change in every month.

These are changes in mean daily sunshine duration for the named months.
