Across calendar months, the unweighted mean difference in monthly mean temperature is an increase of +0.70 °C. This summarizes the set of monthly averages rather than a day-weighted annual average, and it does not imply the same change in every month or describe daytime highs. The largest monthly increase is in July, with a difference of +1.59 °C; that identifies the strongest increase, not a general measure of daytime heat. Mean daily rainfall averaged across calendar months has a difference of +0.17 mm/day. This modest overall increase in the monthly means does not establish that rainfall rose in every month, nor does it describe monthly totals or the number of rainy days. The largest monthly increase is in March, at +1.72 mm/day, while the largest decrease is in December, at -1.78 mm/day. The contrasting monthly changes show why the overall mean should not be read as a uniform shift in daily rainfall.

The largest monthly decrease is in March, with a difference of -0.60 hours/day, while the largest increase is in December, at +0.32 hours/day.
