Climate Change Chart of Río Grande, Argentina

Overview of climate changes

Temperature changes

Monthly mean temperature was higher on average across calendar months in the more recent period, with a difference of +1.25 °C. This unweighted average summarizes the monthly means; it does not imply that every month warmed by the same amount. The largest monthly increase was in June, at +2.50 °C. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in snowfall

Mean daily snowfall averaged across calendar months was lower in the more recent period, with a difference of -0.39 mm/day. This unweighted summary of monthly means describes daily amounts, not monthly snowfall totals. The largest monthly decrease was in July, with a difference of -1.56 mm/day. By contrast, December recorded the largest monthly increase, at +0.11 mm/day; these differences do not mean snowfall changed in the same direction in every month.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months was lower in the more recent period, with a difference of -0.51 hours/day. This is an unweighted average of monthly means, not a day-weighted annual measure. The largest monthly decrease occurred in February, at -0.94 hours/day. The largest increase was in June, with a difference of +0.10 hours/day, so the month-specific shifts were not uniform.

Changes in rainfall

Averaged across calendar months, mean daily rainfall was lower in the more recent period, with a difference of -0.12 mm/day. This unweighted summary of monthly means is not a day-weighted annual average, and it describes daily amounts rather than monthly totals. The largest monthly decrease was in December, with a difference of -0.59 mm/day. In contrast, August had the largest increase, at +0.27 mm/day; these month-specific changes show that the overall average does not describe every month.
