Climate Change Chart of Gaya Island, Malaysia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.48 °C in the more recent period. This is an unweighted average of the monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in April, with a difference of +0.76 °C. This identifies the strongest increase among the reported monthly mean-temperature differences, rather than implying the same change in every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall shows a difference of -0.44 mm/day. This is an unweighted average of monthly means, not a day-weighted annual average, and it describes a difference between period averages rather than a continuous change. The monthly pattern was not uniform: March had the largest decrease, a difference of -1.88 mm/day, while December had the largest increase, a difference of +1.73 mm/day. These figures describe mean daily rainfall, not monthly rainfall totals.

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.46 hours/day in the more recent period. This is an unweighted average of monthly means, not a day-weighted annual average. January recorded the largest monthly decrease in mean daily sunshine duration, with a difference of -1.06 hours/day. This marks the largest reported monthly decrease; it does not mean sunshine changed by that amount in every month.
