Understanding how extremes are changing in long-term rainfall conditions is an important first step for planning appropriate adaptation measures of climate change. The purpose of this study is to investigate an uneven precipitation distribution and hydrometeorological events through the long-term trend of precipitation in Penajam Paser Utara, the new capital city of Indonesia. We used gridded precipitation APHRODITE and Mann-Kendall trend test over 60 years (1954-2015). The results showed the number of consecutive wet days (CWD) is higher than consecutive dry days (CDD). It also makes the number of floods larger than the drought. Even, the trend of rainfall was decreased from 1990 to 2015.
