This study examines the distribution of precipitation across the east coast states of Peninsular Malaysia, specifically focusing on Kelantan, Terengganu, and Pahang, over the period from 1981 to 2019. The analysis aims to understand changes in rainfall patterns due to climate change and weather phenomena, including El Niño and La Niña. Precipitation data are sourced from the APHRODITE dataset, with statistical analysis incorporating indices such as Consecutive Dry Days (CDD) and Consecutive Wet Days (CWD). The research shows a significant increase in total annual rainfall in northern regions, including Kelantan and Terengganu, especially during the La Niña phenomenon. In contrast, southern regions such as Pahang are more susceptible to the impacts of El Niño, leading to drought conditions and reduced rainfall. Visual analysis results, presented through graphs and Geographic Information System (GIS) maps, illustrate temporal and spatial variations in rainfall distribution, revealing a trend of increasing maximum dry days in Pahang and a decrease in dry days in Kelantan. This study provides valuable insights into the risks of floods and droughts, as well as their effects on water resources, agriculture, and the livelihoods of local communities. The findings serve as an important reference for the development of water resource management and disaster mitigation strategies to address the challenges posed by climate change.
