In November 2025, Southeast Asia experienced significant rainfall variability, with several regions seeing extreme departures from the norm. Above-normal rainfall dominated much of Mainland Southeast Asia—including Thailand, Vietnam, and Myanmar—as well as the northern Philippines and eastern Indonesia. These areas saw substantial moisture, with some regions exceeding the average by over 250 mm.

In contrast, below-normal rainfall was concentrated in localized maritime areas, particularly around Singapore, parts of Sumatra, and western Kalimantan. Most of the central Maritime Continent remained near-normal during this transition period.
