Subseasonal Weather Outlook and Review

Wetter conditions are predicted over the southern Maritime Continent in the next fortnight (28 October – 10 November).

Drier conditions are predicted over southeastern Mainland Southeast Asia and parts of the northern half of the Maritime Continent in Week 1 (28 October – 3 November).

Warmer than usual temperature is predicted over the Maritime Continent, apart from the southern region, in the next fortnight (28 October – 10 November). Cooler than usual temperature is predicted over much of eastern Mainland Southeast Asia in Week 1 (28 October – 3 November).

A Madden-Julian Oscillation (MJO) signal was present over the Maritime Continent (Phases 4 and 5) in the middle of October. This MJO signal is predicted to propagate through the Western Pacific (Phases 6 and 7) in Week 1. Most models predict the MJO signal to reach the Western Hemisphere and Africa (Phases 8 and 1) by the start of Week 2 before weakening.

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.
