A Madden-Julian Oscillation (MJO) signal was present over the Western Hemisphere and Africa (Phases 8 and 1) during mid-April. Most models predict the MJO signal to continue propagating eastwards, reaching the Indian Ocean (Phases 2 and 3) by the start of the forecast period, and then weakening over the Indian Ocean during Week 1 (27 April – 3 May).

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.
