Climate Change Chart of Bogor, Indonesia

Overview of climate changes

Temperature changes

Averaged across calendar months, monthly mean temperature shows a difference of +0.97 °C in the more recent period. This is an unweighted mean of monthly averages, not a day-weighted annual mean, and it does not imply that every month changed by the same amount. The largest monthly increase was in September, with a difference of +1.30 °C compared with the earlier reference period. These are monthly mean temperatures, not daytime maximum temperatures.

Changes in rainfall

Averaged across calendar months, mean daily rainfall increased by a difference of +1.66 mm/day. This unweighted mean of monthly averages describes the overall comparison, not a change shared by every month; the figures are daily means rather than monthly rainfall totals. The largest monthly increase occurred in February, with a difference of +5.53 mm/day in mean daily rainfall. By contrast, September had the largest monthly decrease, a difference of -1.66 mm/day. These contrasting monthly differences show why the across-month mean should not be read as a description of each month's change.

Changes in sunshine duration

Mean daily sunshine duration, averaged across calendar months, decreased by a difference of -1.07 hours/day in the more recent period. This is an unweighted mean of monthly averages, not a day-weighted annual average, and it does not mean sunshine fell by the same amount in every month. The largest monthly decrease was in December, where mean daily sunshine duration had a difference of -2.51 hours/day compared with the earlier reference period.
