Subseasonal Weather Outlook and Review

Wetter conditions are predicted over parts of the eastern Maritime Continent in the next fortnight (31 March – 13 April).

Warmer conditions are predicted over much of the equatorial region in Week 2 (7 – 13 April).

A Madden-Julian Oscillation (MJO) signal was present over the Western Pacific (Phase 6) towards the end of March, based on the RMM Index. Most models predict this signal to weaken and become inactive by the start of the forecast period. Models disagree on the evolution of the MJO signal thereafter.

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.
