Climate Change Chart of Puebla, Mexico

Overview of climate changes

Temperature changes

Monthly mean temperature averaged across calendar months shows a difference of +1.32 °C compared with the earlier reference period; this is an unweighted average of the calendar-month means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increases were tied in February / December, each with a difference of +1.92 °C. This identifies the strongest increases among the supplied monthly comparisons, not a change shared by every month.

Changes in rainfall

Mean daily rainfall averaged across calendar months shows a difference of +0.33 mm/day in the more recent period. This unweighted average describes the monthly means, not annual rainfall totals or a uniform change in every month. The largest monthly increase was in September, with a difference of +2.18 mm/day in mean daily rainfall. By contrast, the largest monthly decrease was in May, with a difference of -0.33 mm/day. These are daily mean amounts, not monthly totals, and show that the monthly differences did not all move in the same direction.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months shows a difference of -0.31 hours/day compared with the earlier period. This is an unweighted average of monthly means, not a day-weighted annual figure, and does not imply that sunshine duration decreased in every month. Monthly differences varied: January had the largest increase, a difference of +0.07 hours/day, while September had the largest decrease, a difference of -0.95 hours/day. These figures describe mean daily sunshine hours for those months rather than total sunshine over each month.
