MJO Fortnightly Update
Issued: 11 Feb 2026
No discernible Madden-Julian Oscillation (MJO) signal was present at the start of the second week of March, based on the RMM index. Some models predict an MJO signal to develop over the Western Pacific (Phase 7) by the start of the forecast period, reaching the Western Hemisphere and Africa (Phase 8) during Week 1 (16 – 22 March). There is little agreement on the predicted MJO activity among the rest of the models in Week 1 (16 – 22 March). In Week 2 (23 – 29 March), most models predict no discernible MJO activity.
The qualitative outlook is assessed for the region in general. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
