Subseasonal Weather Outlook and Review

Drier conditions are predicted over the equatorial region in Week 1 (19 – 25 January).

Warmer than usual temperature for this time of the year is predicted over parts of the central and eastern Maritime Continent in Week 1 (19 – 25 January).

Cooler than usual temperature is predicted over parts of southeastern Mainland Southeast Asia and parts of the northeastern Maritime Continent in Week 1 (19 – 25 January).

A Madden-Julian Oscillation (MJO) signal emerged over the Western Pacific (Phase 6) in the second week of January based on the RMM index. Most models predict this signal to continue propagating eastwards, reaching the Western Hemisphere (Phases 8 and 1) by Week 2 (26 January – 1 February).

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.
