Climate Change Chart of Zapopan, Mexico

Overview of climate changes

Temperature changes

Monthly mean temperature was higher by a mean difference of +1.54 °C when averaged across calendar months; this is an unweighted comparison of the monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in February, with a difference of +2.20 °C. This identifies the strongest 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 -0.14 mm/day, indicating a lower mean in the more recent period; this unweighted comparison does not describe every month or a day-weighted annual total. The largest monthly decrease occurred in June, at a difference of -1.19 mm/day. By contrast, the largest increase was in September, with a difference of +0.69 mm/day, showing that the monthly comparisons did not move uniformly. These figures describe mean daily rainfall, not monthly rainfall totals.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.08 hours/day in the more recent period. This is an unweighted summary of monthly means, rather than a day-weighted annual measure. The monthly extremes went in opposite directions: the largest increase was in January, with a difference of +0.29 hours/day, while the largest decrease was in November, at a difference of -0.33 hours/day. These comparisons show the contrast between those months without indicating that all months followed either pattern.
