Climate Change Chart of Santiago de los Caballeros, Dominican Republic

Overview of climate changes

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of -0.32 mm/day. This unweighted average of monthly means summarizes the comparison across calendar months; it is not a daily-total comparison or a monthly rainfall total. The largest monthly decrease in mean daily rainfall was in October, at a difference of -1.45 mm/day. In contrast, March had the largest monthly increase, with a difference of +0.76 mm/day; these distinct monthly results show why the overall mean difference should not be read as applying to every month.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.56 °C compared with the earlier reference period; this is an unweighted average of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase in mean temperature was in June, with a difference of +1.11 °C. This identifies the strongest increase among the supplied monthly comparisons, not a change shared by every month.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.40 hours/day compared with the earlier reference period. This summarizes monthly means rather than describing every month's change or day-to-day sunshine variability. The largest monthly decrease in mean daily sunshine duration occurred in March, with a difference of -0.70 hours/day; this is the strongest monthly decrease in the supplied comparison, not a measure of daily variability.
