Climate Change Chart of Boca Chica, Dominican Republic

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.39 °C compared with the earlier reference period. This is an unweighted mean of the monthly means, not a day-weighted annual average, and it does not imply the same change in every month or describe daytime maximum temperatures. The largest monthly increase in mean temperature was in September, at a difference of +0.63 °C. This identifies the strongest increase among the supplied monthly differences, rather than a change applying uniformly across the year.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.30 mm/day compared with the earlier reference period. This unweighted mean summarizes monthly means; it is not a day-weighted annual average or a monthly rainfall total, and it does not indicate that rainfall decreased in every month. The monthly differences were mixed: May had the largest decrease, a difference of -2.16 mm/day, while November had the largest increase, at +1.78 mm/day. These are differences in mean daily rainfall, not monthly totals, and describe the standout monthly changes rather than daily conditions throughout either month.

Changes in sunshine duration

Across calendar months, mean daily sunshine duration was unchanged at the displayed precision, with a difference of 0.00 hours/day. This is an unweighted summary of monthly means, not a day-weighted annual average; the rounded equality does not establish that every month was unchanged or that there was no difference beyond the displayed precision. Monthly differences varied: June had the largest increase in mean daily sunshine, at +0.49 hours/day, while November had the largest decrease, at -0.36 hours/day. These monthly mean daily hours describe average sunshine duration, not the conditions on every day.
