Wetter conditions are predicted over parts of Sumatra, Malay Peninsula and western Borneo in the first week (16 – 22 November).

Warmer conditions are predicted over much of Mainland Southeast Asia during the next two weeks (16 – 29 November). Warmer conditions are also predicted over parts of Java, southern Borneo and southern Sulawesi in the first week (16 – 22 November), with conditions easing by the second week (23 – 29 November).

An MJO signal is present over the Western Hemisphere and Africa (Phase 8). Most models predict the MJO to continue propagating eastwards, weakening over the Indian Ocean (Phases 2 and 3).

 
The outlook is assessed for the region in general, where conditions are relative to the average conditions for the corresponding time of year. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
