Subseasonal Weather Outlook and Review

Wetter conditions are predicted over parts of the northern ASEAN region in Week 1 (9 – 15 June), in particular over central and eastern Mainland Southeast Asia and the Philippines. Wetter conditions are also predicted over much of the southern ASEAN region in Week 2 (16 – 22 June).

Warmer than usual temperatures are predicted over most of the southern ASEAN region in Week 1 (9 – 15 June).

There were signs of a Madden-Julian Oscillation (MJO) signal developing over the eastern Maritime Continent (Phase 5) during the beginning of June. Most models predict the MJO signal to propagate eastwards to the Western Pacific (Phases 6 and 7) by the start of the forecast period before decaying by the end of the first week.

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.
