Climate Change Chart of Port of Spain, Trinidad and Tobago

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.45 °C in the more recent period; this unweighted mean of monthly means does not describe daytime maximum temperatures or imply that every month changed by the same amount. The largest monthly increase was in June, with a difference of +1.90 °C compared with the earlier reference period.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of -2.12 mm/day compared with the earlier reference period. This is an unweighted comparison of monthly means, not a day-weighted annual average or a monthly rainfall total, so it does not mean rainfall declined by the same amount in every month. The largest monthly decrease in mean daily rainfall occurred in June, with a difference of -5.39 mm/day.

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; that rounded result does not establish that every monthly value was unchanged. The monthly differences show a more mixed pattern: June had the largest increase, a difference of +1.25 hours/day, while October had the largest decrease, a difference of -0.76 hours/day. These are differences in mean daily hours, not totals for the months.
