Climate Change Chart of Réunion, France

Overview of climate changes

Temperature changes

Monthly mean temperature was higher by an average difference of +0.14 °C across calendar months in the more recent period; 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 May, with a difference of +0.36 °C. By contrast, the largest monthly decreases were tied in January / November, each with a difference of -0.18 °C; these monthly comparisons do not imply that every month changed in the same direction.

Changes in rainfall

Mean daily rainfall increased by an average difference of +3.31 mm/day averaged across calendar months in the more recent period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and it describes daily amounts rather than monthly rainfall totals. The largest monthly increase was in January, where mean daily rainfall showed a difference of +8.23 mm/day. That monthly result is a comparison between reference periods, not evidence of a continuous change over time.

Changes in sunshine duration

Mean daily sunshine duration was lower by an average difference of -0.57 hours/day averaged across calendar months in the more recent period. The comparison uses an unweighted average of monthly means, rather than a day-weighted annual average. The largest monthly decrease occurred in January, with a difference of -1.13 hours/day in mean daily sunshine duration. This identifies the strongest monthly decrease in the supplied comparison, not a pattern shared by every month.
