Climate Change Chart of Medina, Saudi Arabia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +2.36 °C in the more recent period; this is an unweighted average of the monthly means, not a day-weighted annual figure or a measure of daytime maximum temperatures. The largest monthly increase was in August, where the difference was +3.32 °C. This identifies the strongest increase among the supplied monthly comparisons, not a uniform change across all months.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +0.04 mm/day. This unweighted average of monthly means is not a day-weighted annual average, and the daily measure should not be read as a monthly total. The largest monthly increase in mean daily rainfall occurred in January, with a difference of +0.31 mm/day. By contrast, March recorded the largest monthly decrease, a difference of -0.22 mm/day; these contrasting monthly changes show why the mean does not describe every month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -0.27 hours/day in the more recent reference period. This is an unweighted mean of monthly values rather than a day-weighted annual measure. The largest monthly decrease was in August, with a difference of -0.68 hours/day. That marks the strongest supplied monthly decrease, while the average change does not imply the same difference in every month.
