Flood in DKI Jakarta is one of the unsolved problems until now. Historical data that recorded show the worst floods in DKI Jakarta are in 1996, 2002 and 2007. The floods are caused by extreme rainfall occurrence, therefore, this research was conducted to obtain the projected extreme rainfall events in Jakarta in the period from 2011 until the year 2035, so that potential flooding can be estimated and taken into the Jakarta administration to make policy adaptation measures. The LARS-WG is used in this study to generate daily rainfall in the present and the future. Meteorological station of Tanjung Priok DKI Jakarta and Observatory Meterorological station had complete and good enough data, so that the two stations were chosen as observation stations representing DKI Jakarta area in this study. Ekstrem rainfall conditions in DKI Jakarta fluctuate compared with baseline and peak found in the period 2011 to 2015. The probability of flooding is highest in the second period form 2016 to 2020, with the rainfall is around 180 mm.
