Probolinggo is a port city on Java Island's northern coast (Indonesia), with area approx 57 km2 (22 mi2) and population around 225,000. The city is located on one of the main highways across Java Island, and has a harbor port used mainly by fishing ships.
Like the most part of northern East Java province, Probolinggo has a large Madurese population. Under Dutch East Indies colonial administration, and especially in the 19th century, the city was a profitable regional center for refining and exporting sugar. Today sugar remains a major product of the region. Probolinggo is famous for its mangoes. Strong dry-season winds (July through September) help mango trees pollinate. Formerly, the city produced grapes.
