Climate Change Chart of La Romana, Dominican Republic

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.52 °C compared with the earlier reference period. This is an unweighted average of the month-by-month means, not a day-weighted annual average, and describes the overall monthly means rather than daytime maximum temperatures. The largest monthly increase in mean temperature occurred in June, with a difference of +0.86 °C. This identifies the strongest increase among the supplied monthly differences; it does not mean that every month warmed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of -0.10 mm/day. This unweighted mean summarizes the monthly means, rather than day-weighted annual rainfall or monthly totals, and should not be read as a uniform change in every month. The largest monthly decrease in mean daily rainfall was in May, with a difference of -2.14 mm/day. In contrast, November recorded the largest monthly increase, a difference of +1.90 mm/day. These month-specific daily-mean differences show that the changes varied by month; they are not monthly rainfall totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration was unchanged at the displayed precision, with a difference of 0.00 hours/day. This unweighted average of monthly means does not establish that sunshine duration was unchanged in every month. Monthly differences nevertheless went in both directions: June had the largest increase, with a difference of +0.39 hours/day, while November had the largest decrease, with a difference of -0.33 hours/day. These figures describe mean daily sunshine hours for those months, not the duration on every individual day.
