Climate Change Chart of Iribarren (Barquisimeto), Venezuela

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.65 °C compared with the earlier reference period; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in September, with a difference of +2.35 °C. That identifies the most pronounced increase among the supplied monthly comparisons, rather than implying that every month warmed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -0.31 mm/day compared with the earlier reference period. This is an unweighted average of calendar-month means, not a day-weighted annual average, and the daily measure should not be read as a monthly rainfall total. Monthly changes were not uniform: May had the largest decrease, a difference of -1.37 mm/day, while September recorded the largest increase, a difference of +0.30 mm/day. These extrema describe differences between the reference periods for those months; they do not establish a continuous change over time or indicate that the same shifts occurred in every month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, shows a difference of +0.13 hours/day compared with the earlier reference period. The figure is an unweighted mean of monthly means, not a day-weighted annual average. The largest monthly increase occurred in May, at a difference of +0.79 hours/day, whereas the largest decrease was in October, at a difference of -0.26 hours/day. These month-specific differences show that the average change varied across the calendar; they do not describe every day or imply a continuous trend between the reference periods.
