The rainiest cities in Cambodia receive the highest annual precipitation, creating lush green landscapes and abundant water resources. Koh Kong leads with 161.5 inches of precipitation annually.

High rainfall supports diverse ecosystems, extensive park systems, and reliable water supplies. These cities often feature vibrant gardens, green spaces, and agricultural communities that benefit from consistent moisture throughout the year.

While abundant rainfall supports lush environments, it can also bring challenges including flooding risks, high humidity, and more frequent overcast days. Many rainy cities have adapted with robust drainage systems, covered public spaces, and a cultural embrace of indoor activities.
