Climate Change Chart of Puerto Toro, Chile

Overview of climate changes

Temperature changes

The monthly mean temperature difference averaged across calendar months was +1.16 °C; this is an unweighted comparison of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in June, at +2.70 °C, while December had the largest decrease, -0.06 °C. These are the largest changes in their respective directions, not a description of every month's difference.

Changes in snowfall

Mean daily snowfall averaged across calendar months had a difference of +0.79 mm/day. This unweighted comparison of monthly means summarizes the periods without implying that snowfall changed by the same amount in every month; these are daily averages, not monthly totals. The largest monthly increase occurred in September, at +3.32 mm/day, while the largest decrease was in May, at -1.60 mm/day. These opposing monthly differences provide context for the average, but do not represent every month's snowfall comparison.

Changes in rainfall

Mean daily rainfall averaged across calendar months had a difference of -0.08 mm/day. This unweighted mean of monthly means describes a broad comparison between the reference periods, not a change that necessarily applied in each month; the figures are daily averages rather than monthly totals. Among individual months, the largest increase was in March, with a difference of +0.35 mm/day. The largest decrease occurred in December, at -1.01 mm/day, showing that the monthly differences were not uniform in direction.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.90 hours/day. This is an unweighted summary of monthly means, not a day-weighted annual figure or evidence that each month had less sunshine. The largest monthly decrease was in January, with a difference of -1.50 hours/day. That identifies the strongest decrease, rather than implying the same difference in other months.
