A seasonal wind pattern often bringing prolonged heavy rain.

The summer monsoon brings weeks of heavy rain to the region.

A sparse dry–wet–dry sequence of the same coastal field makes the recurring rain-bearing wind pattern visible, using windsocks rather than ambiguous palm silhouettes to establish airflow.
Etymology

The Arabic word meant an annually recurring season, including a suitable time for sailing. It became associated with seasonal Indian Ocean winds; the heavy rain brought by India's summer monsoon added the familiar rainy-season connection.
