For the second half of December 2019, drier conditions are expected in some parts of the region, including northern Philippines, southern Viet Nam and southern Thailand. In Java, wetter conditions are expected in the last week of the month.

Most parts of the Mekong sub-region are expected to experience warmer conditions during the coming fortnight. Warmer conditions are also predicted for the areas surrounding the Java Sea, but are expected to ease in the second week of the fortnight.

The outlook is assessed for the region in general. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
