Figure 2: Temperature Outlook

For the first half of June 2019, drier than average conditions are expected to persist over Myanmar.

For the rest of the northern ASEAN region, the prevailing drier than average conditions are likely to ease.

During the forecast period, the MJO that is currently active in the western hemisphere and Africa is forecast to propagate eastwards over the Indian Ocean. The presence of the MJO in Week 1 may bring wetter than average conditions over parts of the equatorial ASEAN region, including Sumatra, southern Peninsular Malaysia and south-western Borneo. However, drier than average conditions conditions can be expected over the areas surrounding Java Sea and Banda Sea.

Warm conditions are expected to continue over most of the northern ASEAN region.

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.
