Subseasonal Weather Outlook and Review

Wetter conditions are predicted over much of Mainland Southeast Asia in Week 1 (12 – 18 May). Wetter conditions are also predicted over parts of the southern Maritime Continent in Week 1.

Warmer than usual temperatures are predicted over parts of the central and western Maritime Continent in the next fortnight (12 – 25 May).

There was no discernible Madden-Julian Oscillation (MJO) signal by the end of the first week of May. Most models predict no MJO activity during the forecast period.

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.
