Climate Change Chart of Bridgetown, Barbados

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.92 °C compared with the earlier reference period; this unweighted comparison of monthly means does not describe daytime maximum temperatures or imply that every month changed by the same amount. The largest monthly increase in mean temperature was recorded in September, at +1.22 °C. This identifies the strongest increase among the supplied monthly differences, rather than a change applying throughout the year.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -2.07 mm/day compared with the earlier reference period. This is an unweighted mean of monthly averages, not a day-weighted annual figure or a monthly rainfall total. The largest monthly decrease in mean daily rainfall occurred in August, with a difference of -4.28 mm/day. It marks the largest decrease among the supplied monthly comparisons; it does not mean that rainfall fell by this amount in every month or on every day.

Changes in sunshine duration

Mean daily sunshine duration changed by +0.02 hours/day when averaged across calendar months. This small aggregate difference describes the unweighted monthly means, not a uniform shift in daily sunshine across the year. The largest monthly increase in mean daily sunshine was in June, with a difference of +0.53 hours/day. In contrast, the largest monthly decrease was in October, at -0.45 hours/day; these are month-specific differences, not changes that apply to every day.
