Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.14 °C; this is an unweighted mean of monthly means, not a day-weighted annual average. The largest monthly increase was in January, with a difference of +2.09 °C. These figures describe monthly mean conditions, not daytime maximum temperatures, and the mean difference does not imply that every month changed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +1.31 mm/day. This unweighted average of monthly means describes daily amounts, not monthly rainfall totals, and does not mean that rainfall increased in every month. The largest monthly increase was in July, with a difference of +4.11 mm/day, while March had the largest monthly decrease, a difference of -0.32 mm/day. These monthly contrasts show that the overall mean conceals variation in the direction and size of the differences.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration had a difference of -0.69 hours/day. This is an unweighted average of monthly means, rather than a day-weighted annual figure, and does not indicate an identical difference in every month. The largest monthly decrease occurred in July, with a difference of -2.23 hours/day. Both observations concern mean daily hours, so they describe average sunshine duration rather than the conditions on every individual day.
