Climate Change Chart of Kampong Cham, Cambodia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature showed a difference of +1.01 °C compared with the earlier reference 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 +1.53 °C. This identifies the strongest increase among the supplied monthly comparisons, rather than implying that every month changed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of +1.13 mm/day compared with the earlier reference period. This is an unweighted mean of monthly averages, not a day-weighted annual average, and the figures describe daily means rather than monthly rainfall totals. The largest monthly increase in mean daily rainfall occurred in July, with a difference of +2.73 mm/day. By contrast, February recorded the largest monthly decrease, a difference of -0.25 mm/day. These monthly extremes show that the overall mean difference does not describe the change in every month.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration showed a difference of -0.63 hours/day compared with the earlier reference period. This is an unweighted comparison of monthly means, not a day-weighted annual average. The largest monthly decrease in mean daily sunshine duration was in July, with a difference of -1.94 hours/day. This marks the strongest decrease among the supplied monthly comparisons and should not be read as the same change applying to every month.
