Climate Change Chart of Laayoune, Morocco

Overview of climate changes

Temperature changes

Across calendar months, the unweighted mean difference in monthly mean temperature was +0.90 °C in the more recent period. This summarizes differences among the calendar-month means; it is not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in October, at +1.50 °C compared with the earlier reference period. That identifies the strongest monthly increase, not a change shared by every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall differed by +0.02 mm/day between the reference periods. This is an unweighted comparison of monthly means, not an annual total or a day-weighted average; the rainfall values describe daily amounts rather than monthly totals. The largest monthly increase in mean daily rainfall occurred in October, with a difference of +0.23 mm/day. By contrast, January had the largest monthly decrease, a difference of -0.13 mm/day. These extrema show that the monthly differences were not uniform, and do not imply that either change applied throughout its month.

Changes in sunshine duration

Across calendar months, mean daily sunshine duration had an unweighted mean difference of -0.24 hours/day. This describes the aggregate of monthly means, rather than a day-weighted annual average or a change that necessarily occurred in every month. The largest monthly decrease was recorded in September, at a difference of -0.58 hours/day compared with the earlier reference period. In January, the largest monthly increase was a difference of +0.09 hours/day. These are monthly mean daily hours, so they describe average conditions rather than daily variability.
