Plain Language Summary: The Indo-Pacific climate modes have important impacts on Indonesian climate. While the influences of the canonical El Niño–Southern Oscillation (ENSO), ENSO Modoki, and Indian Ocean Dipole (IOD) on Indonesian rainfall are statistically significant, their modulation due to the Interdecadal Pacific Oscillation (IPO) has not been understood. It is found that IOD influences are enhanced during the negative phase of IPO. On the other hand, we found no evidence that the IPO modulates the Indonesian rainfall responses to canonical ENSO and ENSO Modoki.
