Subseasonal Weather Outlook and Review

Wetter conditions are predicted over much of Mainland Southeast Asia and the Philippines in Week 1 (24 – 30 June). These wetter conditions are predicted to persist in Week 2 (1 – 7 July), although with less confidence over the Philippines.

Warmer than usual temperature is predicted over the southern half of Southeast Asia in the next fortnight (24 June – 7 July).

No Madden-Julian Oscillation (MJO) signal was present in mid-June based on the RMM index. Most models predict no significant MJO activity 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.
