In April 2025, drier-than-normal conditions dominated most of Southeast Asia, particularly over Indonesia, Malaysia, Brunei Darussalam, Timor-Leste, and Singapore. Significant rainfall deficits were also observed across parts of the Philippines, southern Thailand, and southern Viet Nam.

The rest of the region experienced near normal rainfall conditions.
