Climate Change Chart of Punta Cana, Dominican Republic

Overview of climate changes

Temperature changes

Monthly mean temperature was higher by a difference of +0.81 °C averaged across calendar months in the more recent reference period; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was shared by September / October, with a difference of +1.01 °C compared with the earlier period. That identifies the strongest increase among the reported monthly differences, rather than describing every month or a continuous trend.

Changes in rainfall

Mean daily rainfall had a difference of -0.24 mm/day averaged across calendar months, indicating a lower unweighted average of the monthly means in the more recent period; these are daily averages, not monthly rainfall totals. The month-to-month pattern was not uniform: May had the largest decrease, a difference of -1.98 mm/day, while November recorded the largest increase, a difference of +1.61 mm/day. These extrema describe the reported monthly comparisons and do not imply that rainfall changed in the same direction in every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months was lower by a difference of -0.11 hours/day in the more recent reference period. This is an unweighted comparison of monthly means, rather than a day-weighted annual figure. Monthly differences varied around that average: the largest decrease occurred in November, at a difference of -0.45 hours/day, whereas May had the largest increase, at a difference of +0.22 hours/day. These comparisons concern mean daily hours and do not establish a continuous change or the direction of change in every month.
