Climate Change Chart of Quepos, Costa Rica

Overview of climate changes

Changes in rainfall

Mean daily rainfall averaged across calendar months shows a difference of -5.46 mm/day compared with the earlier period. This unweighted mean describes the monthly averages, not monthly rainfall totals, and does not mean every month was drier. The largest monthly decrease occurred in December, where the difference was -15.61 mm/day; this marks the most pronounced monthly decrease in the supplied facts, not a continuous rainfall trend.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.45 °C compared with the earlier reference period; this unweighted mean summarizes monthly averages rather than daytime maximum temperatures or a change in every month. The largest monthly increase was in March, with a difference of +1.31 °C. That identifies the strongest monthly increase in the supplied comparison, not a continuous change between the reference periods.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of +0.19 hours/day in the more recent period. This unweighted mean across monthly averages does not imply that sunshine increased in every month. The monthly changes went in both directions: July had the largest increase, a difference of +0.74 hours/day, while April had the largest decrease, a difference of -0.59 hours/day. These monthly contrasts describe the reference-period comparison and do not establish a continuous pattern between them.
