For rainfall, wetter conditions are expected over much of the southern ASEAN region in the next fortnight (13 – 26 June). Drier conditions are expected over southern Mainland Southeast Asia in Week 1 (13 – 19 June).

For temperature, cooler than usual temperatures are expected over much of the western and central equatorial region in the next fortnight (13 – 26 June).

A Madden-Julian Oscillation (MJO) signal was present in the Western Hemisphere and Africa (Phases 8 and 1) in the second week of June based on the RMM Index. Most models predict this MJO signal to decay in Week 1 with no significant MJO activity for the rest of 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.
