Subseasonal Weather Outlook and Review

Wetter conditions are predicted over much of the equatorial region in Week 2 (8 – 14 September).

No significant regional temperature anomalies are predicted in the next fortnight (1 – 14 September).

A Madden-Julian Oscillation (MJO) signal propagated from the Indian Ocean (Phases 2 and 3) towards the Maritime Continent (Phase 4) in the second half of August. Most models predict this signal to decay by the start of September, with no significant MJO activity predicted 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.
