Subseasonal Weather Outlook and Review

Wetter conditions are predicted over parts of the southeastern Maritime Continent in Week 1 (10 – 16 July) and much of Mainland Southeast Asia in Week 2 (17 – 23 July). Wetter conditions are also predicted over much of the Philippines in the next fortnight (10 – 23 July).

Drier conditions are predicted over parts of the western and central equatorial region in Week 2 (17 – 23 July).

Warmer than usual temperature is expected over much of the northern ASEAN region in Week 1 (10 – 16 July). Warmer temperatures are then predicted over much of the southern ASEAN region in Week 2 (17 – 23 July).

No clear Madden-Julian Oscillation (MJO) signal was present in the first week of July based on the RMM Index. Most models predict no significant MJO signal during the next fortnight.

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.
