Climate Change Chart of Kuching, Malaysia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.81 °C compared with the earlier reference period. This is an unweighted comparison of monthly means, not a day-weighted annual average, and it describes mean conditions rather than daytime maximum temperatures. The largest monthly increase was in December, with a difference of +1.02 °C. That marks the strongest increase among the reported monthly temperature differences; it does not mean every month changed by the same amount.

Changes in rainfall

Mean daily rainfall, averaged across calendar months, shows a difference of +3.57 mm/day in the more recent period. This unweighted mean across calendar-month means describes typical daily amounts in the comparison, not monthly rainfall totals or a day-weighted annual average. The largest monthly increase occurred in February, where mean daily rainfall had a difference of +6.30 mm/day. This identifies the strongest reported monthly increase, rather than implying that rainfall rose by this amount in every month.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, had a difference of -1.47 hours/day compared with the earlier reference period. This is an unweighted comparison of monthly means, so it summarizes the calendar-month averages rather than a day-weighted annual total. The largest monthly decrease was in December, with a difference of -1.89 hours/day. The monthly result highlights where the decrease was greatest; it should not be read as the same change applying to every month.
