Climate Change Chart of Rabat, Morocco

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.16 °C compared with the earlier reference period. This is an unweighted mean of monthly means, not a day-weighted annual average, and it describes the aggregate rather than every month; it also refers to mean temperature, not daytime maximum temperatures. The largest monthly increase was in May, with a difference of +0.93 °C. In contrast, the largest monthly decrease was in March, at a difference of -0.58 °C. These selected monthly contrasts show that the overall mean does not represent the change in every month.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, had a difference of -0.02 mm/day. This unweighted mean of monthly means is not a day-weighted annual average, and it should not be read as a change in monthly totals or as a uniform difference throughout the year. The largest monthly increase in mean daily rainfall occurred in March, at a difference of +0.56 mm/day, while the largest monthly decrease occurred in December, at a difference of -0.54 mm/day. These are changes in daily averages for the named months, not totals for those months, and they illustrate month-specific differences rather than a consistent pattern across all calendar months.

Changes in sunshine duration

Mean daily sunshine duration averaged across calendar months had a difference of -0.35 hours/day compared with the earlier reference period. This is an unweighted average of monthly means, not a day-weighted annual figure, so it describes the aggregate across calendar months rather than the change in sunshine in each individual month. The largest monthly decrease in mean daily sunshine duration was in March, with a difference of -0.59 hours/day. This identifies the strongest decrease among the monthly comparisons; it does not imply that every month had the same change.
