Climate Change Chart of Santa Marta, Colombia

Overview of climate changes

Temperature changes

The mean difference in monthly mean temperature, averaged across calendar months, was +1.61 °C compared with the earlier reference period; this is an aggregate of monthly means, not a measure of daytime highs or a change experienced in every month. April had the largest monthly mean-temperature increase, a difference of +2.07 °C. That identifies the strongest monthly increase among the supplied comparisons, not a continuous rise between the reference periods.

Changes in rainfall

Mean daily rainfall showed an across-calendar-month difference of -3.91 mm/day. This summarizes monthly averages of daily rainfall, rather than monthly rainfall totals, and does not mean that every month was drier. The largest monthly decrease in mean daily rainfall was in October, with a difference of -10.12 mm/day. This figure describes the change in the daily mean, not the number of rainy days or the chance of rain on a particular day.

Changes in sunshine duration

Mean daily sunshine duration increased by +0.29 hours/day averaged across calendar months. The mean describes an aggregate of monthly daily averages, not a guarantee of brighter conditions on any individual date. The largest monthly sunshine increase was in May, at a difference of +1.30 hours/day; by contrast, March recorded the largest decrease, a difference of -0.16 hours/day. These extrema show that monthly differences were not uniform.
