Climate Change Chart of Bandung, Indonesia

Overview of climate changes

Changes in sunshine duration

Averaged across calendar months, mean daily sunshine duration shows a difference of -0.87 hours/day in the more recent period. This is an unweighted summary of monthly means, so it does not establish the change in every month. The largest monthly decrease occurred in December, with a difference of -2.22 hours/day. By contrast, August recorded the largest increase, a difference of +0.19 hours/day; these are monthly mean daily sunshine durations, not total hours for the month.

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +1.38 °C in the more recent period; this is an unweighted mean of monthly means, not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in September, with a difference of +2.06 °C. This identifies the strongest increase among the monthly means, rather than implying that every month warmed by the same amount.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of +0.18 mm/day in the more recent period. This unweighted summary of monthly means describes daily rainfall amounts, not monthly rainfall totals, and does not mean that rainfall increased in every month. The monthly pattern includes a difference of +1.39 mm/day in April, the largest increase, while September had the largest decrease, a difference of -1.65 mm/day. These contrasting monthly changes show why the small overall mean difference should not be read as a uniform shift across the calendar.
