Figure 2: Temperature Outlook


For the first fortnight of March 2020, there is an increased chance of wetter conditions over northern Viet Nam and most parts of the southern Maritime Continent. These conditions are expected to ease gradually in Week 2. Drier conditions are expected over northern Sumatra, Peninsular Malaysia, southern parts of Thailand and the Philippines throughout the fortnight.

For temperature, warmer conditions are expected over most parts of Southeast Asia.

Some models predict a weak Madden-Julian Oscillation (MJO) emerging over the Maritime Continent in the first week of March. This development may contribute to the wetter conditions in the southern Maritime Continent predicted by the models.

The 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.
