Rain season
Surabaya's wet season (November–April) is driven by the northwest monsoon, with December–February the most intense months. East Java has a more pronounced dry season (May–October) than western Indonesia — Surabaya can go months without significant rain in the dry season. Annual rainfall averages 1,600mm; urban flooding is a recurring challenge during monsoon peaks.
